PHOSPHORUS-MOLYBDENUM COMPOUND, METHOD FOR PRODUCING SAME AND A LUBRICANT ADDITIVE AND LUBRICANT COMPOSITION CONTAINING THE COMPOUND

摘要

Disclosed is a lubricant additive capable of providing an antioxidant which enables a lubricant composition to have long drain intervals, while reducing specific components such as metal contents and phosphorus atoms. Also disclosed is a lubricant composition containing such a lubricant additive. Specifically disclosed is a phosphorus-molybdenum compound represented by the following general formula (I) where R1, R2 and R3 independently represent a hydrocarbon group having 1-20 carbon atoms.
