Abstract

Abstract Vegetable oils such as corn oil, peanut oil, and soy oil are reacted with polyamines to form a mixture containing amides, imides, half esters, and glycerol with subsequent treatment with a strong acid such as sulfonic acid to produce a product mix that has good detergent properties in fuels and lubricants.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 89 words
A composition useful as a detergent additive package for lubricants and fuels prepared by reacting multiamine with vegetable oil to obtain a first product mixture, said vegetable oil selected from among triglycerides of long-chain monocarboxylic acids of the formula ##STR3## wherein R is an aliphatic radical of about 10 to about 25 carbon atoms said first product mixture further reacted with sulfonic acid to obtain a second product mixture said second product mixture dissolved in an amount of hydrocarbon solvent sufficient to maintain said second product mixture in solution.
Claim 2
Dependent Claim 89 words
A composition useful as a detergent additive package for lubricants and fuels prepared by reacting multiamine with vegetable oil to obtain a first product mixture, said vegetable oil selected from among triglycerides of long-chain monocarboxylic acids of the formula ##STR3## wherein R is an aliphatic radical of about 10 to about 25 carbon atoms said first product mixture further reacted with sulfonic acid to obtain a second product mixture said second product mixture dissolved in an amount of hydrocarbon solvent sufficient to maintain said second product mixture in solution.
Claim 3
Dependent Claim 30 words
A composition of claim 1 wherein the multiamines have the general formula H 2 N(CH 2 CH 2 NH) x H where x is an integer between 2 and 10.
Claim 4
Dependent Claim 30 words
A composition of claim 1 wherein said vegetable oils are selected from among the group consisting of cottonseed oil, peanut oil, soybean oil, corn oil, rapeseed oil, and coconut oil.
Claim 5
Dependent Claim 10 words
A composition of claim 1 wherein said multiamine is polyethyleneimine.
Claim 6
Dependent Claim 20 words
An additive package useful as detergent additive for lubricants and fuels comprising a composition of claim 1 and a demulsifier.
Claim 7
Dependent Claim 59 words
A method for reducing engine deposits in an internal combustion engine comprising the addition of a detergent fuel additive package of claim 1 to the hydrocarbon fuel for the engine, said fuel detergent being added in an amount effective to reduce engine deposits and using said hydrocarbon fuel with fuel detergent additive as fuel in an internal combustion engine.
Claim 8
Independent Claim 89 words
A method for producing a detergent additive package for lubricants and fuels comprising: reacting multiamine with vegetable oil to obtain a first product mixture, said vegetable oil selected from among triglycerides of long-chained monocarboxylic acids of the formula ##STR4## wherein R is an aliphatic radical of about 10 to about 25 carbon atoms, further reacting said first product mixture with sulfonic acid to obtain a second product mixture, and dissolving said second product mixture in an amount of hydrocarbon solvent sufficient to maintain said second product mixture in solution.
Claim 9
Independent Claim 89 words
A method for producing a detergent additive package for lubricants and fuels comprising: reacting multiamine with vegetable oil to obtain a first product mixture, said vegetable oil selected from among triglycerides of long-chained monocarboxylic acids of the formula ##STR4## wherein R is an aliphatic radical of about 10 to about 25 carbon atoms, further reacting said first product mixture with sulfonic acid to obtain a second product mixture, and dissolving said second product mixture in an amount of hydrocarbon solvent sufficient to maintain said second product mixture in solution.
Claim 10
Dependent Claim 30 words
A method of claim 7 wherein the multiamines have the general formula H 2 N(CH 2 CH 2 NH) x H where x is an integer between 2 and 10.
Claim 11
Dependent Claim 30 words
A method of claim 7 wherein said vegetable oils are selected from among the group consisting of cottonseed oil, peanut oil, soybean oil, corn oil, rapeseed oil, and coconut oil.
Claim 12
Dependent Claim 11 words
A method of claim 7 wherein said multiamine is polyethylene amine.
Claim 13
Dependent Claim 21 words
A method of claim 7 further comprising the admixing of a demulsifier with said second product mixture dissolved in hydrocarbon solvent.
Claim 14
Dependent Claim 64 words
A method for reducing engine deposits in an internal combustion engine comprising the addition of a detergent fuel additive package prepared by the method of claim 7 to the hydrocarbon fuel for the engine, said fuel detergent being added in an amount effective to reduce engine deposits in using said hydrocarbon fuel with fuel detergent additive as a fuel in an internal combustion engine.
