Sulphur coupled hydrocarbyl derived mercaptobenzothiazole adducts as multifunctional antiwear additives and compositions containing same.

摘要

Sulfur-coupled hydrocarbyl-derived mercaptobenzothiazole adducts have been found to be effective multifunctional antiwear additives for fuels and lubricants. The adducts are prepared by reacting a long-chain olefin with a sulfur source and thereafter coupling the reaction product with a mercaptobenzothiazole.
