Description

[Detailed description of the invention]

This invention relates to additive compositions used in lubricants and normally liquid fuels. In particular, this invention relates to additive compositions derived from the interaction of unsubstituted succinic acylating agents or aliphatic hydrocarbon-based substituted acylating agents and ether amines, concentrates thereof, and additive compositions thereof. lubricants and normally liquid fuels containing the same. Lubricants and normally liquid fuels are known to corrode various materials with which they come into contact. For example, normally liquid fuels accumulate significant amounts of water during storage and later contact metal surfaces in the environment in which they function, resulting in rust and corrosion. Water is also known to be a common contaminant in engine crankcase lubricants. Water may form from the oxidation of lubricating oil or may exit the combustion chamber as a blow byproduct of the burning fuel. In addition to causing rust and corrosion, the presence of this water appears to promote the deposition of mayonnaise-like sludge. This type of sludge is very problematic in that it adheres tenaciously to metal surfaces and is not removed by filtration. Corrosion inhibitors and dispersants are commonly added to lubricants and fuels to overcome the corrosive properties of lubricants and fuels, which are typically liquid, and to improve the dispersion properties of lubricants. Many substances have been developed for this purpose. For example, imidazoline salts of mono- and dicresyl phosphate (U.S. Pat.
3736110), alkyl or alkenyl succinic acid and N of alkyl or alkenyl succinic acid
- mixtures with aminoalkyl- or N-hydroxyalkyl-substituted imidazoline salts (U.S. Pat.
3282836), metal alkyl or alkoxy metal alkyl ester tetrapropenyl succinates (U.S. Pat. No. 3,485,858), and polymerized olefin substituted succinate esters (U.S. Pat. No. 3,381,022).
etc. Broadly speaking, the additive compositions of this invention include (A) at least one unsubstituted or aliphatic hydrocarbon substituted succinic acylating agent and (B) the formula RO-( _CH2 ) _o - _NH2 ( where n is from 1 to about 6, and R is a hydrocarbon group). In a preferred embodiment, the additive composition of the present invention comprises (A) an aliphatic hydrocarbon group-substituted succinic acylating agent, wherein the aliphatic hydrocarbon group has about 4 to about 100 carbon atoms. and (B) ethers in which n is about 2 to about 4 and R is an aliphatic hydrocarbon group having 1 to about 26 carbon atoms. It is a product produced by the interreaction of a reactant mixture consisting of an amine. In a further preferred embodiment, the additive composition of this invention comprises (A) an alkenyl-substituted succinic acylating agent in which the alkenyl substituent has from 8 to 30 carbon atoms; and (B) n is about 2 to about 4 and R is a straight or branched chain alkyl group having about 8 to about 22 carbon atoms. be. In a more preferred embodiment, the additive composition of this invention comprises (A) an alkenyl-substituted succinic acylating agent in which the alkenyl substituent contains about 9 to about 15 carbon atoms;
(B) produced by the interreaction of a mixture of reactants consisting of an ether amine in which n is about 2 to about 4 and R is a straight or branched chain alkyl group having about 10 to about 15 carbon atoms. It is a product. In a most preferred embodiment, the additive composition of this invention comprises (A) an alkenyl-substituted succinic anhydride in which the alkenyl substituent contains about 12 carbon atoms; and (B) n is 3; It is a product prepared by the interreaction of a mixture of reactants consisting of an ether amine in which R is a branched alkyl group containing about 13 carbon atoms. The present invention includes lubricant or fuel compositions containing large amounts of a lubricant or normally liquid fuel and small amounts of the additives described above, as well as concentrates of additive compositions. In this specification, the term "hydrocarbon group" refers to a group having a carbon atom directly connected to the remainder of the molecule and having primarily hydrocarbon characteristics, and includes the following. (1) Hydrocarbon group. i.e. aliphatic (e.g. alkyl or alkenyl), alicyclic (e.g. cycloalkyl or cycloalkenyl), aromatic, aliphatic or alicyclic substituted aromatic, aromatic substituted aliphatic or alicyclic, etc. A cyclic group in which the ring is completed via another part of the molecule (i.e., any two substituents listed above can constitute an alicyclic group). Such groups are known, for example methyl, ethyl, propyl, butyl, octyl, decyl, dodecyl, cyclohexyl, phenyl, tolyl, benzyl and the like. (2) Substituted hydrocarbon group. That is, groups containing non-hydrocarbon substituents that do not alter the predominant hydrocarbon character of the group. For example, there are those containing a hydroxyl group, an alkoxy group, a nitro group, and a carbalkoxy group. (3) Hetero group. That is, groups having primarily hydrocarbon character, but containing atoms other than carbon in the chain or ring. Heteroatoms are well known;
Examples include nitrogen, oxygen, and sulfur. The additive compositions of this invention are complex products obtained by the mutual reaction of at least two different reactive components. Component (A) is an unsubstituted or aliphatic hydrocarbon substituted succinic acylating agent;
(B) is an ether amine. Component (A) is the structural formula

[expression] or

[Formula] (where R' is hydrogen, or about 4 to about
100, preferably from about 8 to about 30, most preferably from about 9 to about 15 carbon atoms); Its anhydrous form. Although there are no particular restrictions on the origin of the aliphatic hydrocarbon substituent, this substituent is generally derived from various olefinic monomers such as ethylene, propylene, butylene, hexene, octene, decene, etc., and oligomers and polymers of these monomers. Derived from polymers and low molecular weight polymers. For example, dimers, trimers and/or tetramers of propylene or butylene can be used. Preferred are aliphatic hydrocarbon-based substituted succinic acylating agents. These are well known and can be manufactured by known methods. One particularly useful method is to react the monoolefin monomers or oligomers described above with maleic anhydride at 100°C to 200°C with or without a catalyst to obtain the corresponding substituted succinic anhydride. It is. The monoolefins used here are 1-butene, 1-hexene, 1-
Even if the alpha position is unsaturated like octene and 1-decene, 2-butene, 3-pentene,
The intermediate position may be unsaturated, such as 4-octene. The same is true for oligomers. This monomer may be replaced by an alkyl halide which can be substituted on the saturated acid anhydride or its free acid. The aliphatic hydrocarbon substituents may be saturated or unsaturated, linear or branched, and may contain polar groups as long as the proportion is not large enough to alter the hydrocarbon properties of the substituent. Representative examples of polar groups are halo, carbonyl, nitro and similar groups. Component (B), the ether amine, has the formula RO-( _CH2 ) _o - _NH2 , where n is about 1 to about 6 and R is a hydrocarbon group. Preferably, n is about 2 to about 4 and R is a saturated or unsaturated, straight or branched chain aliphatic hydrocarbon group having from 1 to about 26 carbon atoms. More preferred ether amines are those in which n is about 2 to about 4, more preferably 3, and R has about 8 to about 22, more preferably about 9 to about 15 carbon atoms. A typical ether amine is SURFAM
