THE DISCLOSURE
This invention relates to a novel multipurpose detergent mixture or blend for addition to gasoline. The novel amine and polyisobutene phenol multipurpose detergent composition of matter shows excellent activity as a car-buretor detergent~ induction system detergent (~ deposit reduction),-combustion chamber detergency and~ in addi-tion~ provides effective rust inhibition when used in automotive gasoline fuels at low concentrations.
The novel composition of matter of this appli- ~;
cation comprises, in the broad range, about 20 to 300 ppm (parts per million on a weight basis in gasoline) of the amine adduct blended or mixed with 100 to 650 ppm of the polyisobutene phenol, as an additive for gasoline, and, more preferably~ about 50 to 100 ppm of the amina adduct blended or mixed with 200 to 300 ppm of the polyisobutene phenol, as an additive for gasoline. The ppm figures are based on their use in gasoline, the gasoline being a dis-tillate hydrocarbon fuel having a major proportion of a hydrocarbon base fuel distilling within the gasoline dis-tillation range. Stated otherwise, the novel composition of matter (of this application), for addition to gasoline, `~
comprise~ on a 1000 barrels of gasoline basis, in the broad range, about 5 lbs. to 75 lbs. of the amine adduct blended or mixed with 25 lbs. to 162 5 lbs. of a polyiso-butene phenol and~ more preferably, about l5 lbs. to 25 lbs. of the amine adduct b]ended or mixed with 50 lbs. to 75 lbs. of the polyisobutene phenol.
The novel composition of matter of this applica- ;
tion is a mixture or blend of a polyisobutene phenol/

The amine adduct may also be described as the reaction product of a polyisobutene phenol with epichlorohydrin followed by amination with ethylene diamine.
It is an object of the present invention to - provide a detergent motor fuel which will have certain -carburetor detergent properties and which will clean up and maintain the cleanliness of the carburetor and also the remainder of the fuel induction system, such as the valves and ports, and reduce the octane requirement in-crease of an internal combustion engine by reducing the buildup of combustion chamber deposits. It is another object of the present invention to provide a detergent fuel which will maintain a low level of hydrocarbon and carbon monoxide exhaust gas emissions and which will avoid the use of phosphorus-containing additives. It is still a further object of the present invention to provide a ;~ ;
detergent fuel which has other desirable properties~ such `~ ~
: . ~.
as rust and corrosion protection, water demulsibility `
properties, anti-icing prop~rties, etc. It is a further ob-ject of the present invention ~o provide a multi-functional gasoline additive or additive combination effective in inhibiting the formation of intake valve deposits in addi-tion to being effective as carburetor detergents and which can be used at relatively low concentrations (and thus at relatively low cost), for example, at a total treating level~ i.e.~ the mixture of the amine adduct and the poly--isobutene phenol, of about 120 to 950 parts per million (ppm on a weight basis in the gasoline) and, more prefer-ably~ 260 to 400 ppm.
~ 3 .)Q~ - -~' ~

ll~7680;~

There are, Or course, other detergent motor fuel compositions available today, but they generally suffer from one or more deficiencies. Either they are used at very high concentrations, for example, something of the order of 4000 ppm; or if used at the use leYels in which we are interested, the available formulations suffer from one or more defects.
It has been conceived and demonstrated that the reaction products of certain alkylphenols, epichloro-hydrin and amines blended together with the polyisobutenephenol show excellent carburetor, induction system and combustion chamber detergency and, in addition~ provide effective rust inhibition when used in automotive gasoline fuels at low concentrations, i.e., between about 120 to 950 ppm and, more preferably, between about 250 to ~00 ppm. In addition to their activity as fuel additives~
these compounds are also potential ashless rust inhibitors and dispersants for use in lubricating oils. The pre-ferred products are the N,~ Bis[3-(p-H35-polyîsobutyl-20 phenoxy)-2-hydroxypropyl] ethylene diamine blended ~ith ~
a polyisobutene phenol. The PIB is our abbreviation for ~ i a polyisobutene generically of any molecular weight. The H35 is the commercial designation for Amoco's polyisobutene of Min ~'670. The structural formula for the preferred product is as follows:

' -3a- ~
~.

OH OH
O-CH2cHcH2NHcH2~I2NHc~2cHcH2-l P~BH35 PIBH35 The PI ~ 35 component (which can also be written simply as R) may have a number average molecular weight (~) of about 500 to 2000 and~ more preferably, about 6CO
to 1500. Optionally, some of the polyisobutene may be in the ortho position where it is denominated Rl. Rl may, therefore~ simply be the same as R~ i.e., a polyisobutene -radical of number a~erage molecular weight of about 500 to 2000 and, more preferably, about 600 to 1500; or R
may alternatively simply be hydrogen, i.e.~ H.
According to one aspect of the present inven-tion~ therefore, we provide a normally liquid~ multi- `~
I functional additive composition for addition to a leaded~
¦ - low leadj or unleaded gasoline, i.e., to a distillate ! 15- hydrocarbcn fuel comprising a major proportion of a hydro-carbon base fuel distilling within the gasoline distilla-ti~n range. This additive provides carburetor, induction system and combustion chamber detergency, rust inhibition and good handling properties to a higher degree than nor-mally found with typical current first generation multi-purpose carburetor detergents of the alkyl ammonium phosphate or polyolefin succinimide type. The increased performance we are seeking is necessitated in part by the 10768~Z .~

advent of emissions control hardware which must,re~ain ,.
deposit-free if the new automobiles are to remain within the EPA emissions specifications for 50,000 miles as re-quired for vehicle certification.
Although there are many carburetor detergents~
on the market~ to our knowledge~ only one, Chevron F-310 9 can be classified as a true second generation additive possessing the broad based activity we are seeking and have achieved. However~ F-310 is recommended at a high treating level of ~OOO ppm 9 and that may exceed the indus-try's handling or economic capabilities. Therefore9 we feel there is currently no additive available which is completely acceptable in terms of economics, treating level and performance.
The pre~erred chemical amine adduct gasoline additive c ~ ound disclosed in C~dian Application 242,180 is pre-pared by the following reaction sequence:
a) Phenol is alkylated with polyisobutene, i.e., polyisobutylene, of Mn ~670 (Amoco H35) using an acid catalyst.
b) The polyisobutylphenol is converted to, ~ ~;
the sodium phenoxide using sodium hydroxide and then reacted with epichlorohydrin.
c) Two moles of the epichlorohydrin adduct are reacted with et~ylene diamine to form the desired product.

by means of a special "Y" intake manifold with t~o one-barrel- carburetors, which can be independently adjusted and activated. With this arrangement, a separate test fuel can be evaluated by each carburetor which feeds four of the eight cylinders via the non-interconnected intake manifold. -The carburetors are modified with removable aluminum sleeves in order to facilitate weighing of the deposits which accumulate in the throttle body area. The severity of the test is adjusted to an appropriate level by recycling the entire amount of blowby gases, approxi-mately 90-110 c.f.h., to the top of the air cleaner so that each carburetor receives an equal volume of these gases. Equal intake mixture flow through each carburetor is adjusted during the first hour of operation of means of intake mani~old differential pressure and C0 exhaust gas analysis. The fo110wing test cycle and operating con-ditions are employed:

(B) IND~ICTION SYST~M DEPOSIT ENGINE TEST
En~ine Test Procedure The Induction System Deposit Test (ISDT) which is used to evaluate the ability of gasoline addit ves or mixtures of additives to control induction system deposits, is run using a new air-cooled~ single cylinder, ~ cycle~
2.5 ~.P. Briggs and Stratton engine for each test. The engine is run for 150 hours at 3000 rpm and ~.2 ft. lbs.
load? with a 1 hour shutdown every 10 hours to check the oil level. Carbon monoxide exhaust emission measurements - are made each hour to insure that a constant air to fuei (A/F) ratio is being maintained.
Upon completion of a test run, the engine is partially disassembled~ and the intake valve and port are rated and valve and port deposits are collected and weighed.
The test procedure used to measure octane nu~lber requirement increase, the Co~ustion Chamber Deposit Englne Test~ is described below.

En~ine Test Procedure The Combustion Chamber Deposit Engine Test ~-tCCDET) is used to evaluate the ability of a gasoline additive or mixture of additives to control or reduce the ~:
octane number require~ent increase (ONRI) in an internal combustion engine. The test is run using a 1972 Chevrolet 350 CID V-8 engine equipped with a two-barrel carburetor ., and a 1972 Turbo ~ydr~matic 350 transmission which is cor-nected to a 101~-2 WIG dynamometer equipped with a 200.3 lb.-ft.2 inertia wheel.

One Or the unique features Or the products of this invention is that they are one of the few non-ionic compounds that provide a high degree of rust inhibition.
This is an important~feature in a gasoline additive since ionic rust inhibitors, i.e.~ carboxylic and phosphoric acid salts, tend to aggravate the problem of induction system deposits. In addition, a non-ionic or ashiess ~
20 rust inhibitor is a key-component in formulating an ash- ~ ;
less engine oil. Therefore, the products of this inven-tion may find utility as lubricant additives as well as gasoline ~uel additives. The general structure of the-novel com~ound$ Or the invention in Applica-tion No. 242,180 may be expressed as follows:

A further, prefèrredj aspect of the invention as ~ ~;

wherein PIBH35 is polyisobutyl of number average molecular weight of about 670~ and Rl is either PIBH35 or hydrogen.
The :invention as set forth in the Principal Dis- :
closure hereof, in another aspect, resides in a motor fuel :
composition comprising ~ .~ ~ ~:

; (~) a major proportion by weight of gasoline~ and ¦-(2) a minor proportion by weight, i.e. about 20 ¦-to 300 ppm, of the above-defined amine adduct (a) ad~ix~d or f~ ...... .. .

~ 6~0;2 blended with about 100 to 650 ppm of the polyisobutene phenol.
I Now,-according ~o a further broad aspéct of the --prè~ent invention~ as set forth more fully hereinafter in this Supplementary Disclosure, there is provided a mult~urpose, additive for a hydrocarbon fuel, a lubricating oil, or a mix-ture of a hydrocarbon fuel and a lubricating oil, comprising a mixture of .
(1) the reaction product of (a) a glycidyl ether ~-compound of the formula (R6~ OCH2CH - CH2 where R6 is an aliphatic hydrocarbon group having at least 8 carbon atoms and m is 1-3, and (b) an amine having at least :
one amino group having at least one active hydrogen atom, and (2) a polyalkylene phenol. .
Also provided by the invention as described in this Supplementary Disclosure is a composition comprising a blend o~
(A) a major proportion by weight of a hydrocarbon fuel, a lubricating oil, or a mixture of a hydrocarbon fuel and a lubricating oil, and ;

one amino group having at least one active hydrogen atom, and .
(2) a polyalkylene phenol.

:~, ' . ': ' .

~076~2 Thus, it has been found that the additives as orig-inally disclosed herein need not be restricted only to what is set forth in the Principal Disclosure, in the following respects:
(a) the amine reactants wh;ch may be used;
(b) the chain length of the alkyl group on the phenol;
(c) the extent of substitution of the glycidyl ether alkyl phenol on the amine; and ~ d) the number of alkyl substituents on the phenol.
Detergent motor fuel and lubricating oil addi-tives available today generally suffer from one or more deficiencies. ~ither they are used at very high concen_ trations, for example, of the order of 4000 ppm, or if used at lower, more economical levels, their detergency and other desirable properties are substantially diminished or lost.
The motor fuel detergency properties relate to ability of the additive to clean up and maintain the cleanliness of the carburetor and other elements of the fuel induction system, ~uch as the intake valves and ports, and to reduce the octane requirement increase of an internal combustion engine by reducing the buildup of combustion chamber deposits . Another property is the ability of the additive to maintain a low level of hydro- ~-carbon and carbon monoxide exhaust gas emissions so that phosphorus-containing additives are not required. Still other desirable properties include rust and corrosion ~'"',, -22- ;

.~

1~768()2 protection, water demulsibility properties, anti-icing properties, and the like.
It has been conceived and demonstrated that mixtures of (1) the reaction products of certain substi-tuted phenols, epichlorohydrin and amines, and (2) a polyalkylene phenol show excellent carburetor, induction system and combustion cham~er detergency and, in addition, provide effective rust inhibition when used in hydrocarbon fuels at low concentrations, i.e., about 20 to 300 ppm of reaction product (1) and about 100 to 650 o the poly-alkylene phenol (2) and, more preferably, about 60 to 100 ppm of (1) and about 200 to 300 ppm of (2). Stated on another basis, the novel composition of matter (of this application), for addition to gasoline for example, com- `
prises on a 1000 barrels of gasoline basis, in the broad range, about 5 lbs. to 75 lbs. of the amine adduct (1) blended or mixed with 25 lbs. to 162.5 lbs. of a polyiso-butene phenol and, more preferably, about 15 lbs. to 25 lbs. of the amine adduct blended or mixed with 50 lbs. to `~
7~ lbs. of the polyisobutene phenol. As hydrocarbon motor fuel (such as gasoline or diesel fuel) additives, the mixtures of the invention act to control spark plug fouling and thus help to keep the spark plugs relatively clean and free of deposits. ~
In addition to their activity as fuel additives, ~ ~`
these mixtures are also ashless rust inhibitors and ',: ` .

~4)'76802 dispersants for use in lubricating oils at concentrations of about 0.1 to 10% by weight, preferably about 0.5 to 8 by weight, wherein the ratios of (1) to (2) are about equivalent to those set forth above.
According to a preferred aspect of the present invention, there is provided a normally liquid, multi-purpose additive mixture for addition to a leaded, low lead, manganese or unleaded gasoline, i.e., to a distillate hydrocarbon fuel comprising a major proportion of a hydrocarbon base fuel distilling within the gasoline ;
distillation range. The additive mixture provides carbu-retor, induction system and combustion chamber detergency, rust inhibition and good handling properties to a high degree and at relatively low concentrations (and thus at relatively low cost), for example, at a total treating level, i.e., the mixture of the amine adduct and the polyisobutene phenol, of about 120 to 950 parts per million (ppm on a weight basis in the gasoline) and, more preferably, 260 to 400 ppm. The increased performance : .
sought is necessitated in part by the advent of emissions control hardware which must remain deposit-free if the new automobilies are to remain within the United States EPA
emissions specifications for 50,000 miles as required for -vehicle certification.
Component (1) of the multipurpose additive of the present invention in its broadest aspect is the reaction `
product of (a) a glycidyl ether compound (I) of the formula: j .

(R )m ~ C~2cH C~ I

where R6 is an aliphatic hydrocarbon group containing at least 8 carbon atoms, m is 1-3, and (b) a primary or ~-secondary monoamine or polyamine, that is, an amine ~;
having at least one amino group having at least one active hydrogen atom. The mole ratio of glycidyl ethèr to amine can be 1:1, less than 1:1 or at least 1:1, depending on -the number of active hydrogen atoms available for reaction, the extent of glycidyl ether substitution desired, and the economics of the reaction considering the ease or diffIculty with which the substitution can take place.
Thus, while ethylene diamine has four active amino hydrogen atoms and theoretically therefore can be tetra-substituted ;
with the glycidyl ether reactant, the degree of substitu- ~ ;
tion is influenced by the number, position and bulk of the R groups. When R , for example, is C8 or Cg and m is 1 or 2, tetra substitution on ethylene diamine occurs with ease. A glycidyl ether compound to amine mole ratio of at least 4:1 is therefore appropriate, although a lower degree of substitution can be achieved by a lower mole ratio, if desired. However, when R is long chain ~;~
alkyl and/or bulkier in configuration, such as polyalkylene of 500 or higher molecular weight, it may be difficult to achieve more than di substitution by the glycidyl ether compound and then primarily only mono substitution on different nitrogen atoms may occur. -~
,~ .
- 25 - `~

1~76~302 The glycidyl ether compound (I) is conveniently prepared by condensing a metal alkoxide of a phenol having 1-3 aliphatic hydrocarbon substituents (R6) with an excess of epichlorohydrin. The carbon content and number of aliphatic hydrocarbon substituents are chosen to provide the required degree of solubility of the final glycidyl ether compound/amine adduct in hydrocarbon fuels or lubri-cating oils.
In this specification unless otherwise stated, molecular weights are number average molecular weights and "alkyl" includes any aliphatic hydrocarbon radical, whether straight or branched chain, derived from an alkane.
A variety of alkyl phenols are commercially available for preparing the glycidyl ether compounds, including octyl phenol, nonyl phenol, dodecyl phenol, octadecyl and pentadecyl phenol, in their various mono, ;, di and tri-substituted forms and isomeric mixtures thereof.
As is well-known, the alkylation of phenol produces a mixture of mono-, di- and tri-alkylated phenols, predomi- ;
nating in ortho and para substituted products. Preferred i" :
products are thosecontaining at least 60% of the alkyl ''~
substituent para to the phenolic hydroxyl group. The mono-alkylated phenol is the preferred product but di- or tri-alkylated products need not be removed from the admixture. -;
The substituted phenols wherein the substituent is poly-alkylene are prepared by methods well-known in the art, for `~
example, by the acid-catalyzed alkylation of phenol with ~ -~
an olefin. They are also readily prepared by polymerizing '"'' :. :~';;'i' :, .

~076802 a low molecular weight mono-olefin containing from about 2 to 10 carbon atoms, such as ethylene, propylene, butylene, pentene and decene, and then alkylating the phenol with the polyolefin. Preferably, the resulting polyalkylene substituent will have a molecular weight of about 500-2000, more preferably about 600-1500, wherein the polyalkylene is the polymerization product of propylene or butene, whether straight or branched chain or mixtures thereof. A pre-ferred R substituent is made by the polymerization of propylene or butene, or mixture thereof, to produce a polyisopropylene or polyisobutene mixture. While the major product of the alkylation is the para substituted, mono polyalkylene phenol, some di- and tri- substitution will also occur. Accordingly, the invention includes the use of such substituted mixed products.
Any amine having at least one amino group having at least one active hydrogen atom may be reacted with the glycidyl ether compounds (I) to form the adducts of the invention. Accordingly, suitable amines include primary and secondary mono and polyamines such as aliphatic amines, aromatic amines, cyclic amines, and heterocyclic amines.
A single amine may also contain both primary and secondary amino groups. The amines may also carry one or more inert substituents, that is, substituents which do not substan-tially affect the reactivity of an amine group toward the glycidyl ether compound nor the properties of the final adducts as multipurpose additives for fuels and lube oils.
Among such relatively inert substituents may be mentioned - 27 - -~

Also, dialkyl amines may be used such as dimethyl amine, diethyl amine, methylethyl amine, methylbutyl amine, di-n-hexyl amine, methyl dodecyl amine, dieicosyl amine, methyl triacontyl amine, dipenta-contyl amine, and the like, including mixtures thereof.
Another useful class is the N-substituted com-pounds such as the N-alkyl imidazolidines and pyrimidines.
Also, aromatic amines having a reactive hydrogen atom ;
attached to nitrogen can be used. These include aniline, ;
N-methyl aniline, ortho, meta and para phenylene diamines, ~-naphthyl amine, N-isopropyl phenylene diamine, and the like. Heterocyclic amines are likewise useful including morpholine, thiomorpholine,-N-(3-aminopropyl)morpholine, ;

including their substituted homologs in which the substi-tuent groups include alkyl, aryl, alkaryl, aralkyl, cyclo-alkyl and the like. '`

where Rl, R2 and R3 independently are hydrogen, Cl-C6 alkyl substituted by -NH2 or -OH, R4 is a Cl-C divalent hydro-carbon radical (alkylene or phenylene), R5 is hydrogen or Cl-C6 alkyl, and n is 0 to about 5. These amines include amines wherein the amino groups are bonded to the same or different carbon atoms. Some examples of diamine reactants where the amine groups are attached to the same carbon atoms of the alkylene radical R4 are N,N-dialkyl-methylen~diamine, N,N-dialkanol-l,l-ethanediamine, and N,N-di(aminoalkyl)-2,2-propanediamine.
Some examples of diamine reactants in which the ~
amine groups are bonded to adjacent carbon atoms of the R4 ~ -alkylene radical are N,N-dialkyl-1,2-ethanediamine, N,N-dialkanol-1,2-propanediamine, N,N-di~aminoalkyl)-2,3-butane-diamine, and N,N-dialkyl-2,3-(4-methylpentane)diamine. ; -Some examples of diamine reactants in which the amine groups are bonded to carbon atoms on the alkylene radical represented by R4 which are removed rom each other by one or more intervening carbon atoms are N,N-dialkyl-1,3-propanediamine, N,N-dialkanol-1,3-butanediamine, N,N-di-(aminoalkyl)-1,4-butanediamine, and N,N-dialkyl-1,3-hexane-diamine. i , Some examples of hydroxyl substituted radicals are 2-hydroxy-n-propyl, 2-hydroxyethyl, 2-hydroxy-n-hexyl, 3-hydroxy-n-propyl, 4-hydroxy-3-ethyl-n-butyl, and the like.

Some examples of amine substituted R , R and R3 radicals are 2-aminoethyl, 2-amino-n-propyl, 4-amino-n-butyl, 4-amino-3,3-dimethyl-n-butyl, 6-amino-n-hexyl, and the like.
Preferred R , R2 and R3 radicals are unsubstituted alkyl radicals such as methyl, ethyl, n-propyl, isopropyl, sec-butyl, n-amyl, n-hexyl, 2-methyl-n-pentyl, and the like.
Some specific examples of diamine reactants are:
N,N-dimethyl-1,3-propanediamine; N,N-dibutyl-1,3-propane-diamine; N,N-dihexyl-1,3-propanediamine; N,N-dimethyl-1,2-propanediamine; N,N-dimethyl-l,l-propanediamine; N,N-dimethyl-1,3-hexanediamine; N,N-dimethyl-1,3-butanediamine;

with ammonia. Most of the above polyamines are co~mercially available.
As indicated, when the amine contains two or more active hydrogen atoms and when more than two moles of the glycidyl ether compound (I) are used in preparing the additives of the invention, poly- substitution can occur.
Accordingly, depending upon the selection of polyamine and ~ ;
glycidyl ether compound and the mole ratios of the react-ants, the reaction product can have none, some, or all of the terminal or internal amino groups of the polyamine substituted. Those skilled in the art will appreciate the fact that in a condensation reaction of the type of this invention, involving a reactant (polyamine) having multiple reaction sites, the reaction product will usually ~ be a mixture of the possible reaction products, although -~ one or more of the products may predominate over the others. Accordingly, it will be understood that the reaction products of the invention include mixed products as well as single products. - As pointed out in the Principal Disclosure, a preferred component (l) of the additive mixtures of the invention is N,N'-bis[3-(p-H35-polyisobutylphenoxy)-2-hydroxy-propyl]ethylene diamine, shown by the structural formula III
where R is hydrogen or PIBH35:

The reaction product may be separated from the hydrocarbon solvent usually employed as the reaction medium or the product may be left in the solvent and the mixture used as a concentrate for blending with a hydro-carbon fuel. If the product is to be used in a heating oil or a lubricating oil, or even if it is to be used in a motor fuel, a concentrate in neutral oil (about one-third neutral oil and two-thirds amine adduct) is a convenient blending composition. The concentrate may be further dilu-ted, if desired, to contain about 10-60~ by weight of amine adduct.
Experience with a large number of product com- ~-pounds of the type shown in the reaction scheme above, indicates that a polyisobutene substituent in the molecular weight range of 500-2000 and a polyamine of the ethylene diamine, diethylene triamine type produces the best balance of properties in terms of detergency, rust inhi-bition and handling, when used in admixture with component (2).
The polyalkylene phenol component (2) is used primarily for cost considerations and lowers treating costs. However, component (2) also promotes deposit ;
reduction as shown in the Induction System Test described. `
~omponent (2) is any of the polyalkylene phenols described above as reactants for the preparation of the glycidyl ether compounds (I), such as polyisopropylene phenol or polyisobutylene phenol having a number average ,, !

107~80~

molecular weight of about 500-3000, preferably about 600-1500. The polyalkylene phenols may also be mixtures of two or more of the mono, di and tri-alkylated phenols and any straight or branched chain products resulting from the alkylation of phenol. Component (2) may be present in the additive mixture as material remaining unreacted from the preparation of component ~1), or component (2) may be added separately.
Table IV presents data on the use of an additive mixture of the invention containing an adduct of formula ' III or IV and the polyisobutylene phenol prepared in Example 1, Part A (see pages 14-15 of the Principal Dis-closure). The comparison primarily is with Chevron F-310.
The essential component in Chevron F-310 is believed to ` ~ -be a polybutene amine as described in U.S. Patent 3,438,757. As can be seen from Table III, the mixture of the amine adduct component (1) and the polyisobutene phenol component (2) compares very favorably with com- `
ponent (1) and with the Chevron F-310, when the latter two additives are used alone. It should also be noted from Table IV that the Chevron F-310 is used at a much higher level (1000 lbs. per thousand barrels of gasoline) than is either the amine adduct component or the mixture of component (1) and component (2). A description of test procedures (A) and (B) is given in pages 8-11 of the Principal Disclosure hereof, to which the reader is re~erred.

MS-08 gasoline is used in the slowby Carburetor Detergency Keep Clean Engine Test (Al. Phillips "J" Reference Fuel, an unleaded fuel, is used in the Induction System Test (B).
As stated in page 13 of the Principal Disclosure, one of the unique features of the additive mixtures o~ the invention is that they are one of the few non-ionic additives that provide a high degree of rust inhibition. This is an important feature in a gasoline additive since ionic rust inhibitorsr i.e., carboxylic and phosphoric acid salts, tend to aggravate the problem of induction system deposits. In addition, a non-ionic or ashless rust inhibitor is a key component in formulating an ashless engine oil. Therefore, the mixtures of this invention have utility as natural or synthetic lubricating oil additives as well as motor fuel -additives.
In addition to use in all types of gasoline fuels, the products have multipurpose utility in other liquid hydro-carbon motor fuels, particularly of the diesel and jet engine types, and in heating fuel oils such as furnace oils, burner oils, and the like.
Accordingly, the multipurpose additive mixtures of the invention have valuable utility in two- and four-cycle combustion ignition engines for controlling or reducing car-buretor, induction system and combustion chamber deposits, and for control or reduction of octane number requirement increase, spark plug fouling and power loss; and in compression ignition (diesel) engines for controlling piston and fuel injector deposits, and for reducing smoke emissions and power loss. While optimum use levels in various systems may differ, an advantage provided in common is multifunctional utility at relatively low use levels.
,, i~76802 The fuel or lubricating oils containing an additive mixture of the invention may also be formulated with any of the conventional additives, including antiknock agents, igni-tion accelerators, combustion improvers, power improvers, cold starting aids, autoignition inhibitors, antioxidants, gum inhibitors, corrosion inhibitors, sludge inhibitors, detergents, metal deactivators, stabilizers, dispersants, tetra-ethyl lead ;
stabilizers, stabilizers for metal carbonyls, varnish inhibitors, upper cylinder lubricants, scavengers, octane-requirement-increase depressants, surface ignition inhibitors, spark plug fouling inhibitors, dyes, foam inhibitors, odor inhibitors, odor masking agents, anti-icing agents, decolorizing agents, odorants, identification markers, freezing point depressants, and flammability suppressors.
In the following examples and throughout the specification and claims, all parts and percentages are by weight unless otherwise noted, and R6 is hydrogen or the same as the other hydrocarbon substituent on phenol. These examples illustrate component (1) of the additive mixtures of the in-vention. While not described separately, the polyalkylene phenols reactants used in preparing the amine adduct component " ;~;
(1) may also be used in excess or added separately to component (1) to form additive mixtures of the invention. (Example 1, Parts A-C, appears in pages 14-16 of the Principal Disclosure.) Part A: Polyisopropylphenol To a 5-liter, 4-necked round-bottomed flask fitted with a stopcock on the bottom, a condenser, a stirrer, a thermometer, and an addition funnel, were charged, under nitro-gen, 1150 g (2.0 moles) Ampol C20 polypropylene.

followed by the dropwise addition ~10 minutes) of 102.4 g (0.4 mole) BF3 Phenol complex. The reaction mixture was heated to 95C and held there 5 hours. The reaction mixture was then cooled to 70C, diluted with 600 cc toluene, and a solution of 131.4 g (1.24 moles) Na2CO3 in 1050 cc water was slowly added. The mixture was heated to 80C and the layers were allowed to separate. After discarding the aqueous layer, the organic layer was washed with 100 cc water. The organic layer was then vacuum stripped (180, 0.25 mm) to afford 1260 g (94%) polyisopropylphenol (Mn~ 737).
Part B: Polyisopropylphenyl Glycidyl Ether To a 5-liter, 4-necked round-bottom flask fitted with a condenser, addition funnel, stirrer, and thermometer were charged 1260 g (1.71 moles) above polyisopropylphenol.
