Abstract
The invention relates to an improved process for producing organomolybdenum compositions with high molybdenum content that are highly useful as lubricant additives, in which the process involves reacting a fatty oil with a diamine, followed by reaction with a molybdenum source. The process of the present invention does not require a volatile organic solvent to promote molybdenum incorporation and produces an organomolybdenum composition having a high molybdenum content. In addition, the process can be conducted in the absence of sulfur and phosphorus-containing reactants.
Claims44
A composition comprising the reaction product of a fatty oil, a diamine, and a molybdenum source in which the reaction product is formed in the absence of carbon disulfide and volatile organic solvent.
An oil soluble composition comprising the reaction product of a fatty oil, a diamine, and a molybdenum source, wherein the diamine has the chemical structure:
- wherein x is 1 or 2, and R is an alkyloxyalkylene group represented by —X1—O—X2, wherein X1 is an alkylene of 2, 3 or 4 carbons, and X2 is an alkyl moiety having 3 to 30 carbon atoms, and wherein the fatty oil comprises a triglyceride having fatty acid moieties, and said fatty acid moieties comprise C12 to C22 hydrocarbon chains, and wherein the oil soluble composition includes a molybdenum content of from about 8.1 wt % to about 15 wt %.

- wherein the total base number (TBN) as determined by ASTM D2896 is less than 50 mg KOH/gram.
A process for preparing a molybdenum-containing composition comprising:
- (a) combining a material selected from the group consisting of a fatty oil, vegetable oil, a triglyceride, and glycerol ester of a fatty acid, with a mono-substituted alkylene diamine to produce an aminoamide/glycerol carboxylate mixture;
- and
- (b) combining the mixture from (a) with a molybdenum source in the presence of water.
