Abstract
Hydrocarbyl acid phosphate salts of polyamides having at least one amino group and hydrocarbon fuel compositions containing same. The salts are formed by neutralizing with a hydrocarbyl acid phosphate at least 10% of the amino groups of a polyamide containing from about 2 to about 6 amide groups and at least one amino group. Hydrocarbon fuel compositions containing these salts exhibit desirable properties such as enhanced carburetor detergency and carburetor anti-icing characteristics, improved water tolerance, excellent rust inhibition, and cleaner engine operation while engines operated thereon exhibit reduced hydrocarbon content in the exhaust.
Claims8
A composition consisting essentially of a hydrocarbyl hydrogen phosphate salt of a compound having the formula ##EQU12## wherein m is at least 1 and the sum of n plus m is from 2 to about 6, R is a multivalent hydrocarbon group of about 2 to about 52 carbons, R' is a hydrocarbylene group of about 2 to about 12 carbons, R" is selected from the group consisting of hydrogen and hydrocarbyl groups of about 1 to about 30 carbons, R'" is a hydrocarbyl group of about 2 to about 12 carbons, and at least about 10% of the amino groups contained therein are converted to the hydrocarbyl hydrogen phosphate salt wherein each hydrocarbyl group of the phosphate molecule contains from 1 to about 15 carbon atoms.
A composition consisting essentially of a hydrocarbyl hydrogen orthophosphate salt of a compound selected from the group consisting of ##EQU13## and mixtures thereof wherein R is the C.sub.34 hydrocarbylene portion of the dimer of a polyunsaturated C.sub.18 monocarboxylic fatty acid, R' is tallowyl, each hydrocarbyl group of the hydrocarbyl hydrogen orthophosphate contains from 1 to about 15 carbons, and about 50% to about 90% of the amino groups are converted to the hydrocarbyl hydrogen orthophosphate salt.
