Claim:
A composition comprising: A) a lubricant, and B) at least one reaction product of an acidic organic compound, a boron compound, and a basic organic compound, wherein the reaction product is a metal free detergent and wherein the acidic organic compound is selected from the group consisting of: (A) alkyl substituted salicylic acids, (B) di-substituted salicylic acids, (C) oil soluble hydroxy carboxylic acids, (D) salicylic acid calixarenes, (E) sulfur-containing calixarenes, (F) acids of the formula: wherein R 1 is hydrocarbon or halogen, R 2 is hydrocarbon, and Ar is substituted or unsubstituted aryl, (G) acids of the formula: wherein X and X′ are independently selected from the group consisting of hydrogen, hydrocarbyl, and halogen, R is polymethylene or branched or unbranched alkylene, x is 0 or 1, and R 1 is hydrogen or hydrocarbyl, (H) acids of the formula: wherein R 1 and R 2 are independently selected from the group consisting of hydrogen, hydrocarbyl groups, tertiary alkyl groups, and tertiary aralkyl groups, provided that both R 1 and R 2 are not hydrogen, R 3 and R 4 are independently selected from the group consisting of hydrogen, hydrocarbyl groups, aralkyl groups, and cycloalkyl groups, and x is from 0 to 24, inclusive; and (I) salts of the foregoing acids; and wherein the basic organic compound is selected from the group consisting of N-hydroxyalkyl-N′-alkyl-imidazolines, N-hydroxyalkyl-piperazines, N-hydroxyalkyl-N′-alkyl piperazines, N-hydroxyalkyl-N′-cycloalkyl-piperazines, N-hydroxyalkyl-N′-alkyl hexahydropyrimidines, N-hydroxyalkyl-N′-cycloalkyl hexahydropyrimidines, N-hydroxyalkyl-N′-alkyl hexahydropyridazines, N-hydroxyalkyl-N′-cycloalkyl hexahydropyridazines, N-hydroxyalkyl-piperidines, N-hydroxyalkyl-N′-alkyl-imidazolidines, N-hydroxyalkyl-N′-cycloalkyl-imidazolidines, N-hydroxyalkyl-pyrrolidine, N-hydroxyalkyl-pyrazolidine, N-hydroxyalkyl-hydrogenated 1,2,3,-triazole, N-hydroxyalkyl-hydrogenated 1,2,4,-triazole, N-hydroxyalkyl-hydrogenated indole, N-hydroxyalkyl-hydrogenated carbazole, N-hydroxyalkyl-hydrogenated quinoline, N-hydroxyalkyl-hydrogenated acridine, N-hydroxyalkyl-hydrogenated phenazine, N-oxyalkyl-N′-hydrocarbyl-saturated cyclic diazines, and N-hydroxyalkyl-N′-hydrocarbyl-saturated cyclic diazines.
