Abstract
Compositions suitable as replacements for sulfurized sperm oil as extreme pressure additives in lubricants are obtained by sulfurizing a mixture of at least one fatty acid ester (preferably an oil such as soybean oil), at least one C.sub.8 -.sub.36 aliphatic olefin (preferably an .alpha.-olefin), and, optionally, at least one fatty acid (preferably unsaturated).
Claims7
A sulfurized composition of matter prepared by reacting, at about 100.degree.-250.degree.C., sulfur with a mixture comprising (A) 100 parts by weight of at least one fatty acid ester of a polyhydric alcohol, (B) about 2-50 parts by weight of at least one fatty acid, and (C) about 25-400 parts by weight of at least one aliphatic .alpha.-olefin containing about 8-36 carbon atoms.
