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.
Claims38
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 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:
- 6
- 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.
A process for preparing a molybdenum-containing composition, comprising reacting a fatty oil, a diamine, and a molybdenum source, in the absence of volatile organic solvent.
