  • Process for the preparation of silane polysulfides
    Patent number: 5489701
    Abstract: Sulfur-containing organosilicon compounds useful as coupling agents in vulcanizable rubbers to enhance various properties, including low rolling resistance for automobile tires, are prepared. Preferred compounds include .OMEGA.,.OMEGA.'-bis (trialkoxysilylalkyl) polysulfides. The compounds are prepared by reacting sodium ethoxylate with hydrogen sulfide gas to yield a sodium sulfide solution, and then reacting this product with a slurried mixture of elemental sulfur and chloropropyltriethoxysilane to form the compound 3,3'-bis (triethoxysilylpropyl) tetrasulfide. The use of hydrogen sulfide gas and sodium metal alcoholates provides an efficient and economical process.
