Abstract
Abstract The mechanisms for the reaction of sulfur with alkanes and unsaturated compounds are highly speculative, but generally, unsaturated compounds are much more reactive toward sulfur than alkanes. Sulfur reacts with mercaptans in the presence of basic catalysts, forming polysulfides. Sulfur monochloride and sulfur dichloride react with both unsaturated materials and mercaptans. Sulfurized and sulfurchlorinated unsaturated compounds and mercaptans are used as lubricant additives, refinery catalyst regeneration compounds, steel processing aids, and vulcanization catalysts. Manufacturing methods for sulfurization of unsaturated compounds and mercaptans and for sulfurchlorination of unsaturated compounds or mercaptans are given. These products are normally considered nonhazardous.
