ABSTRACT:
Process of sulfurizing a blend of 90 to 50 and preferably 88 to 70 parts by volume of triglyceride such as lard oil and 10 to 50 and preferably 12 to 30 parts by volume of an ethylenically unsaturated hydrocarbon containing 2 to 24 carbon atoms. The sulfurization is carried out using elemental sulfur. Simultaneous sulfurization and chlorination may be effected by reacting with sulfur monochloride. Phosphosulfurization may also be carried out by addition of small amounts of a phosphorus sulfide to the sulfurized blend followed by heating at 180.degree. F. to 250.degree. F. for from 30 minutes to 10 hours to effect phosphosulfurization. The sulfurization or phosphosulfurization involves reacting at from 350.degree. F. to 445.degree. F. for 20 minutes to 10 hours followed by blowing with a gas at from 125.degree. F. to 250.degree. F. for 30 minutes to 20 hours to remove hydrogen sulfide. The simultaneous sulfurization and chlorination reaction is carried out at from 90.degree. F. to 280.degree. F. for from 20 minutes to 10 hours followed by blowing with a gas at from 125.degree. F. for 30 minutes to 20 hours. The sulfurized oils contain from 7.5 to 25 weight percent sulfur as based on the blend of olefin and triglyceride.
