Abstract

PURPOSE: To provide an extreme-pressure additive which has excellent adsorptive power to metals and give high load resistance with a small amount, consisting of a partial ester of a sulfurized alkenylsuccinic acid obtd. by the reaction of an alkenyl- succinic anhydride with sulfur and a polyhydric alcohol.
CONSTITUTION: One mol of an alkenylsuccinic anhydride having a 6W20C alkenyl group, 0.01W10mol of sulfur and a 2W20C alcohol having at least two OH groups such as ethylene glycol or propylene glycol, are reacted together to produce a partial ester of a sulfurized alkenylsuccinic acid. The resulting partial ester is used as the desired extreme-pressure additive. 0.01W10wt% extreme-pressure additive is incorporated into a synthetic oil and/or a mineral oil having a kinematic viscosity of 10W10,000cSt at 40°C and a viscosity index of 80 or above to provide a high-performance lubricating oil compsn. suitable as turbine oil, engine oil, etc.
