Claims24
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 R18 is hydrogen or a substituted or unsubstituted hydrocarbyl having from 1 to about 30 carbon atoms;
- R19 in each of the x (R19O ) groups is independently a straight or branched C2-C4 alkylene;
- R20 is a bond or a substituted or unsubstituted hydrocarbylene having from 2 to about 6 carbon atoms;
- R21 and R22 are each independently hydrogen, substituted or unsubstituted hydrocarbyl having from 1 to about 30 carbon atoms, —(R23)n—(R19O)yR24, or R21 and R22 together with the nitrogen atom to which they are bonded are joined together to form a heterocyclic group;
- R23 is substituted or unsubstituted hydrocarbylene containing from 1 to about 6 carbon atoms, R24 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 R25 is a substituted or unsubstituted hydrocarbyl having from 1 to about 30 carbon atoms and preferably from about 8 to about 30 carbon atoms;
- R26 in each of the x (R26O) groups is independently a straight or branched C2-C4 alkylene;
- R27 is hydrogen or a straight or branched alkyl group having from 1 to about 6 carbon atoms;
- R28 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 R29 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, R30 in each of the x (R30O) and the y (R30O ) groups is independently a straight or branched C2-C4 alkylene, R31 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 R11 is hydrocarbon or halogen, R12 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, R13 is polymethylene or branched or unbranched alkylene, x is 0 or 1, and R14 is hydrogen or hydrocarbyl,
- (H) acids of the formula:
- wherein
- R15 and R16 are independently selected from the group consisting of hydrogen, hydrocarbyl groups, tertiary alkyl groups, and tertiary aralkyl groups, provided that both R15 and R16 are not hydrogen,
- each R17 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.
29 more elements
A lubricating oil composition comprising:
- (a) an oil of lubricating viscosity, and
