Abstract

Disclosed is a lubricating oil composition comprising the reaction product of a nitrogen containing reactant wherein the nitrogen containing reactant comprises an alkyl di-alkanolamide, an alkyl di-alkanolamine, or mixtures thereof; an acidic molybdenum compound; and a salicylate compound. Also disclosed is a method for operating an internal combustion engine comprising said lubricating composition and a method for preparing a molybdenum containing friction modifier.

First claim

What is claimed is:

1. A lubricating oil composition comprising an oil of lubricating viscosity, and the reaction product of:
a. a nitrogen containing reactant, wherein the nitrogen containing reactant comprises an alkyl di-alkanolamide, bis-ethoxy alkylamide, bis-ethoxy alkylamine, an alkyl di-alkanolamine, or mixtures thereof,
b. an acidic molybdenum compound; and
c. a salicylate compound.

2. The composition of claim 1 , wherein the nitrogen containing reactant comprises a compound having the formula (I) and/or formula (III),

wherein each R individually comprises 1 to 30 carbon atoms and Q is a C 1 to C 4 linear or branched alkylene group.

3. The composition of claim 1 , wherein the alkyl di-alkanolamide comprises a bis-ethoxy alkylamide.

4. The composition of claim 1 , wherein the alkyl di-alkanolamine comprises a bis-ethoxy alkylamine.

5. The composition of claim 3 , wherein the alkyl group in the bis-ethoxy alkylamide is derived from coconut oil.

6. The composition of claim 4 , wherein the alkyl group in the bis-ethoxy alkylamine comprises oleyl, dodecyl, or 2-ethylhexyl group.

7. The composition of claim 1 , wherein the acidic molybdenum compound is selected from the group consisting of molybdic acid, ammonium molybdate, sodium molybdate, potassium molybdates, hydrogen sodium molybdate, MoOCl 4 , MoO 2 Br 2 , Mo 2 O 3 Cl 6 , molybdenum trioxide, and mixtures thereof.

8. The composition of claim 1 , wherein the salicylate compound has the following formula (V):

wherein R 1 , R 2 , R 3 , and R 4 are each independently selected from the group consisting of hydrogen atom, C 1 -C 40 alkyl group, carbocyclic group, heterocyclic group, nitro group, alkoxy group, hydroxy group, nitrile group, thiol group, amide group, amino group, keto group, and ester group; R 5 is a hydrogen atom or C 1 -C 18 alkyl group.

9. A method for operating an internal combustion engine comprising lubricating said engine with a lubricating oil composition comprising
a. a major amount of base oil of lubricating viscosity; and
b. the reaction product of:
i. a nitrogen containing reactant, wherein the nitrogen containing reactant comprises an alkyl di-alkanolamide, an alkyl di-alkanolamine, or mixtures thereof,
ii. an acidic molybdenum compound; and
iii. a salicylate compound.
