Abstract
A lubricating oil additive capable of providing an antioxidant which enables a lubricating oil composition to have long drain intervals, while reducing specific components such as metals and phosphorus atoms, and a lubricating oil composition containing the lubricating oil additive are provided. A phosphorus molybdenum compound represented by the following general formula (1) where R1, R2, and R3 each independently represent a hydrocarbon group having 1 to 20 carbon atoms is also provided.
Claims7
A lubricating oil composition comprising a phosphorus molybdenum compound represented by the following formula (1):
- wherein R1, R2, and R3 each independently represent a hydrocarbon group having 1 to 20 carbon atoms wherein the compound is blended in a lubricating base oil.
A lubricating oil additive comprising a phosphorus molybdenum amine compound obtained by reacting a phosphorus molybdenum compound represented by the following formula (1):
- wherein R1, R2, and R3 each independently represent a hydrocarbon group having 1 to 20 carbon atoms, with an amine compound.
A method of using a phosphorus molybdenum compound represented by the following formula (1):
- wherein R1, R2, and R3 each independently represent a hydrocarbon group having 1 to 20 carbon atoms, as an antioxidant in a lubricating composition, said method comprising contacting the compound with a lubricating base oil.
