ABSTRACT:
A sulfurized composition prepared by sulfurizing a mixture of at least one terpene and at least one other olefinic compound is described. More particularly, sulfurized compositions prepared by sulfurizing a mixture of pine oil and at least one other olefinic compound are described. Such sulfurized compositions are useful as lubricant additive compositions, and more particularly, as additive compositions in industrial and gear lubricants. The compositions when added to lubricants provide lubricants which exhibit improved antioxidant characteristics, nitrile seal compatibility and acceptable color characteristics.
