Abstract:
A process for the sulfurization of triisobutylene and resulting products comprising contacting triisobutylene with sulfur under essentially atmospheric conditions at a temperature between about 360* and 500*F., utilizing a mole ratio of triisobutylene to sulfur of between about 1:4 and 1:2.5 while blowing the reaction mixture during at least a part of said contacting with an inert gas and recovering a sulfurized triisobutylene product containing as a major component a compound of the empirical formula C12H20S3 having substantially reduced corrosive activity to copper coupled with superior EP (extreme pressure) improving properties when incorporated in hydrocarbon lubricating oils such as gear oils and cutting oils.
