LUBRICANT CONTAINING A MOLYBDENUM COMPOUND

摘要

A lubricating composition containing an organic molybdenum compound having excellent oxidation stability that provides lubricity for long periods of time is provided. The lubricant comprises a molybdenum amine compound obtained by reacting a compound containing a hexavalent molybdenum atom with an amine represented by the following formula (1): (see formula 1) wherein R1 represents a hydrogen atom and/or a hydrocarbon group, and each of R2 and R3 is a chain hydrocarbon group having one or more carbon atoms; or the following formula (2) (see formula 2) wherein R4 represents a chain hydrocarbon group having 10 or more carbon atoms, s represents 0 or 1, X and/or Y represents a hydrogen atom, a hydrocarbon group having at least one carbon atom, an alkanol group having 2 to 4 carbon atoms or an alkyl amino group having at least one carbon atom, and X and Y are not hydrogen atoms or hydrocarbon groups at the same time that s is 0. A lubricating composition containing the lubricant is also provided.
