Abstract:
1. A lubricating oil composition comprising: (a) an oil of lubricating viscosity, and (b) an effective amount of at least one reaction product of an acidic organic compound, a boron compound, and an alkoxylated amine, wherein the reaction product is a metal free detergent wherein the alkoxylated amine is selected from the group consisting of (a) an alkoxylated amine represented by general formula: wherein R 18 is hydrogen or a substituted or unsubstituted hydrocarbyl having from 1 to about 30 carbon atoms; R 19 in each of the x (R 19 O ) groups is independently a straight or branched C 2 -C 4 alkylene; R 20 is a bond or a substituted or unsubstituted hydrocarbylene having from 2 to about 6 carbon atoms; R 21 and R 22 are each independently hydrogen, substituted or unsubstituted hydrocarbyl having from 1 to about 30 carbon atoms, —(R 23 ) n —(R 19 O) y R 24 , or R 21 and R 22 together with the nitrogen atom to which they are bonded are joined together to form a heterocyclic group; R 23 is substituted or unsubstituted hydrocarbylene containing from 1 to about 6 carbon atoms, R 24 is hydrogen or a linear or branched alkyl group having 1 to about 4 carbon atoms, n is 0 or 1, and x and y are independently an average number from 1 to about 60; (b) an alkoxylated amine represented by general formula: wherein R 25 is a substituted or unsubstituted hydrocarbyl having from 1 to about 30 carbon atoms and preferably from about 8 to about 30 carbon atoms; R 26 in each of the x (R 26 O) groups is independently a straight or branched C 2 -C 4 alkylene; R 27 is hydrogen or a straight or branched alkyl group having from 1 to about 6 carbon atoms; R 28 is a substituted or unsubstituted hydrocarbyl having from 1 to about 30 carbon atoms, and x is an average number from 1 to about 60; (c) a dialkoxylated amine represented by general formula: wherein R 29 is a linear or branched alkyl, linear or branched alkenyl, linear or branched alkynyl, aryl, or aralkyl group having from about 6 to about 30 carbon atoms, R 30 in each of the x (R 30 O) and the y (R 30 O ) groups is independently a straight or branched C 2 -C 4 alkylene, R 31 is independently hydrogen, or a linear or branched alkyl group having from 1 to about 4 carbon atoms and x and y are independently an average number from 1 to about 40; and mixtures thereof 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 11 is hydrocarbon or halogen, R 12 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 13 is polymethylene or branched or unbranched alkylene, x is 0 or 1, and R 14 is hydrogen or hydrocarbyl, (H) acids of the formula: wherein R each R x is from 0 to 24, inclusive; and
