ABSTRACT:
A process for preparing an oxidized sulfurized isobutylene product having utility as an EP additive. The process comprises the steps of: reacting sulfur monochloride with a stoichiometric excess of isobutylene; reacting the product so produced with an alkali metal monosulfide and free sulfur in an alcohol-water solvent; reacting the product so produced with an aqueous solution containing an alkali metal hydroxide; and reacting the liquid sulfurized isobutylene so produced with a mild oxidizing agent under conditions sufficient to effect the appearance of new infrared frequency bands at 1300 cm.sup.-1 and 1030 cm.sup.-1 indicative of the formation of sulfoxides and sulfones and recovering a liquid oxidized sulfurized isobutylene product which is soluble in a lubricating composition.
