SULPHURISED PHENOL ADDITIVES AND COMPOSITIONS

摘要

Sulphur monochloride and a phenol are reacted to produce an oil-soluble intermediate which is then reacted with an unsaturated organic compound having one or more olefinic or acetylenic bonds to reduce the amount of active sulphur in the intermediate and to leave no excess of hydrocarbon, thereby to produce a low-chlorine, low-active sulphur content oil-soluble sulphurised phenol.
