Definitions
- R is the nitrate ester of hydroxyalkyl having up to five carbon atoms and R is selected from the group consisting of hydrogen, alkyl having up to five carbon atoms, R-stubstituted alkyl having up to ten carbon atoms, the nitrate ester of hydroxyalkyl having up to 10 carbon atoms and R and the nitrate ester of hydroxy substituted alkyl having up to 10 carbon atoms.
- the ester is in turn converted to the alcohol by subjecting it to acid hydrolysis. Our process appears to be operable for all nitrates of this type.
- the nitration of the N-trinitroalkylamino alcohol is carried out using nitric acid as the nitrating agent, generally in the form of a nitrating mix with sulfuric acid, acetic anhydride, phosphorus pentoxide or other dehydrating agent which will not react with the reactants or products to destroy the desired nitrate.
- nitric acid generally in the form of a nitrating mix with sulfuric acid, acetic anhydride, phosphorus pentoxide or other dehydrating agent which will not react with the reactants or products to destroy the desired nitrate.
- nitration reaction at temperatures ranging from about 5 to 25 C.
- the resulting product can be recrystallized by dissolving in cold fuming ni
- the N-nitroN-trinitroalkylaminoalkyl nitrate can be converted to an N-nitro-N-trinitroalkylaminoalkyl ester by reacting the same with an esterifying agent such as acetic anhydride, phthalic anhydride, lower aliphatic acid chlorides, etc., in the presence of an acid esterification catalyst, such as sulfuric acid, benzenesulfonic acid, toluenesulfonic acid, etc.
- the reaction is carried out at low temperatures ranging from about 0 to about 30 C.
- the ester can ordinarily be recovered by cooling the reaction mixture to a temperature of about 0 or below as by pouring the reaction mixture over ice.
- ester is obtained as an oily liquid and it is generally desirable to dry the same by any convenient means such as, for example, dissolving the oily layer in ether, adding magnesium sulfate as a drying agent, removing the drying agent, and then removing the ether by distillation.
- the N-nitro-N-trinitroalkylaminoalkyl ester can beconverted to the corresponding alcohol by hydrolysis in the usual manner. Acids such as hydrochloric, sulfuric, etc. can be employed and generally we prefer to employ reflux temperatures for carrying out the hydrolysis of the ester to obtain the alcohol. Generally We prefer to conduct the hydrolysis in the presence of an inert solvent, such as a lower alkyl alcohol. Following the reaction, the solvent can be removed by distilling in vacuo to obtainthe alcohol as an oily liquid which in some instances crystallizes upon cooling. to dissolve the oily product in a suitable solvent such as ether, and thenremove the solvent by distillation in vacuo to obtain a product oil which crystallizes upon cooling. In other instances, it is necessary to dissolve the oily product in a suitable solvent such as, for example, ether and then crystallize the same by addition of hexane or other suitable material to the ether solution. Ordinarily,
- the product can be recrystallized from any suitable sol depending upon the chain length of the polymer, the" nature of the cross-linking agent, etc.
- These polymers are also stable to shock, heat, etc., to the extent that, as a general rule, additional stabilizers are not required in the propellant mixtures.
- Our monomers are also plasticizers for polymers prepared from our monomer alcohols.

2,987,549 N-NITRO-N-TRINITROALKYLAMINE ALCOHOLS AND DERIVATIVES THEREOF Henry Feuer, Lafayette, Ind., and William A. Swarts, Niagara Falls, N.Y.
No Drawing. Filed Oct. 16, 1958, Ser. No. 767,746 10 Claims. (Cl. 260-584) Our invention relates to novel nitro compounds and more particularly it relates to polynitro amino alcohols and to a process for producing same.
Our new compounds have the following structural formula:
R2 R3(|3R where R is the radical t -NR1C (N02) 3 R is selected from the group consisting of and alkylene having up to five carbon atoms; R is hydroxyalkyl having up to five carbon atoms; R is selected from the group consisting of hydrogen, alkyl having up to five carbon atoms; R is selected from the group consisting of hydrogen, alkyl having up to five carbon atoms, R-substituted alkyl, hydroxyalkyl having up to ten carbon atoms and R-and hydroxy-substituted alkyl having up to ten carbon atoms; and n is a number from 3 to 9.
Compounds which come within the above structural formula include: 2-(N-nitro-N-trinitroethylamino)-etha- 1101, 3 (N nitro-N-trinitroethylamino)-1-propanol, 2- methyl 2 (N-nitro-N-trinitroethylamino)-1,3-propanediol, 2-(N-nitro-N-trinitroethylamino)-1,4-butanediol, 2,3- bis(2-trinitroethylamino)-1,4-butanedoil, 2-propyl-2-[N- nitro N-(2-phenyl-2-trinitropropylamino)] 1,3-propanediol, 3-methyl-3-[N-nitro-N-(2-cyclohexyl-Z-trinitroethylamino)]heptanol, 6-(N-nitro-N-trinitroethylamino)-l-undecanol, 2- [N-nitro-N-(2-trinitrobutylamino) -1-pentanol, 2,6 bis[N-nitro-N-(2-phenyl-2-t1initroethylamino)]1,7- heptanedoil, 2,4-bis[N-nitro-N-(2-cyclopentyl-2-trinitroethylamino)]-2-ethyl-l-hexanol, 5,9-dihydroxymethyl-3,5, 9,1l-tetra(N-nitro-N-trinitroethylamino)tridecane, 2-hydroxybutyl 2,4-bis(N-nitro-N-trinitroethylamino)-l-hex anol, 2,9-diethy1-2,4,7,9-tetra[N-nitro-N-(2-trinitropropyl) amino]-1-l0-decanedoil, etc.
Generally our process for producing our new compounds consists of esterifying a nitrate having the following structural formula:
where R is the nitrate ester of hydroxyalkyl having up to five carbon atoms and R is selected from the group consisting of hydrogen, alkyl having up to five carbon atoms, R-stubstituted alkyl having up to ten carbon atoms, the nitrate ester of hydroxyalkyl having up to 10 carbon atoms and R and the nitrate ester of hydroxy substituted alkyl having up to 10 carbon atoms. The ester is in turn converted to the alcohol by subjecting it to acid hydrolysis. Our process appears to be operable for all nitrates of this type.
The nitrates untilized in forming the alcohols of our invention are easily prepared by the process of our copending application, U.S. Serial No. 713,512, now abandoned. In this application we claim a process wherein 1 Patents 2,582,048 and 2,548,803 wherein nitro substituted 7 2,987,549 Patented June 6, 1961 2 polynitroamino alcohols are nitrated to form the abovedescribed polynitroamino nitrate.
The nitration of the N-trinitroalkylamino alcohol is carried out using nitric acid as the nitrating agent, generally in the form of a nitrating mix with sulfuric acid, acetic anhydride, phosphorus pentoxide or other dehydrating agent which will not react with the reactants or products to destroy the desired nitrate. Generally we prefer to carry out the nitration reaction at temperatures ranging from about 5 to 25 C. Following completion of the nitration reaction, We can generally obtain the N- nitro-N-trinitroalkylaminoalkyl nitrate as a solid by cooling the reaction mixture to a temperature of about 0 or below as by pouring the reaction mixture over ice. The resulting product can be recrystallized by dissolving in cold fuming nitric acid and then cooling to the low temperatures indicated by any means, including pouring the nitric acid solution over ice.
The N-nitroN-trinitroalkylaminoalkyl nitrate can be converted to an N-nitro-N-trinitroalkylaminoalkyl ester by reacting the same with an esterifying agent such as acetic anhydride, phthalic anhydride, lower aliphatic acid chlorides, etc., in the presence of an acid esterification catalyst, such as sulfuric acid, benzenesulfonic acid, toluenesulfonic acid, etc. The reaction is carried out at low temperatures ranging from about 0 to about 30 C. The ester can ordinarily be recovered by cooling the reaction mixture to a temperature of about 0 or below as by pouring the reaction mixture over ice. Generally the ester is obtained as an oily liquid and it is generally desirable to dry the same by any convenient means such as, for example, dissolving the oily layer in ether, adding magnesium sulfate as a drying agent, removing the drying agent, and then removing the ether by distillation.
The N-nitro-N-trinitroalkylaminoalkyl ester can beconverted to the corresponding alcohol by hydrolysis in the usual manner. Acids such as hydrochloric, sulfuric, etc. can be employed and generally we prefer to employ reflux temperatures for carrying out the hydrolysis of the ester to obtain the alcohol. Generally We prefer to conduct the hydrolysis in the presence of an inert solvent, such as a lower alkyl alcohol. Following the reaction, the solvent can be removed by distilling in vacuo to obtainthe alcohol as an oily liquid which in some instances crystallizes upon cooling. to dissolve the oily product in a suitable solvent such as ether, and thenremove the solvent by distillation in vacuo to obtain a product oil which crystallizes upon cooling. In other instances, it is necessary to dissolve the oily product in a suitable solvent such as, for example, ether and then crystallize the same by addition of hexane or other suitable material to the ether solution. Ordinarily,
the product can be recrystallized from any suitable sol depending upon the chain length of the polymer, the" nature of the cross-linking agent, etc. These polymers are also stable to shock, heat, etc., to the extent that, as a general rule, additional stabilizers are not required in the propellant mixtures. Our monomers are also plasticizers for polymers prepared from our monomer alcohols.
As previously indicated, low molecular weight polymers preparedfrom the monomers of our invention are fluids. These propellants are generally rich in fuel elements and as such can be utilized as a fuel in the process of US. Patent 2,537,526 where tetranitromethane and hexani-T troethane are used as oxidants and liquid nitro parafiins are used as fuels; in the processes described in U.S.
In some instances it is necessary al-iphatic compounds having more than one nitro group per carbon atom were used as oxidants and nitro-substituted compounds having less than one nitro group per carbon atom were used as fuels in -monopropellantsysterns; or in the similar process of US. Patent- 2,590,009.
We have discovered that generally solid polymers 'prepared from our alcohols and various isocyanates and amines'can be dissolved in polar solvents, such as'i'dimethylformamide and lower nitro alkanes, such as tetranitromethane, and, as such, are operative as fuels 'in' the above-described processes. Other solvents which can be used to liquify our polymers include dimethylsulfoxide, Cellosolve, acetonitrile, lower alkanols, nitro esters and nitro ethers.
Rubber-like materials can be prepared by'interaction of our alcohols with cross-linking agents such as diisocyanates, variouspolycarboxylic'acids, such as succinic acid, tartaric acid, maleic acid, malic acid, etc.
Our monomers form polymers with tetranitrodicarboxylic acids which can be prepared-by interacting a tetranitro compound with methylacrylate, and hydrolyzing the resulting tetranitro ester to form'the acid.
a Our solid polymers can beimixed wih various oxidant salts, such as ammonium nitrate,'ammonium perchlorate,
lithium perchlorate, etc. to obtain solid heterogeneouspropellants having specific impulses on theorder of that of Ballistite.
The following examples are offered to illustrate the production of our new compounds. We do not intend to be limited to the specific materials, proportions, conditions, etc. shown, rather we intend to include all equivaients obvious to those skilled in the art.
