Procedure
Into a clean, dry 300 cubic centimeter high pressure reactor were added 58 grams (0.23 moles) of beta-triethoxysilylthiopropionamide product (containing 14% beta-cyanoethyltriethoxysilane starting material) and 2.5 weight percent of cobalt trisulfide. The reactor was sealed, pressurized to 1100 psig with hydrogen, and placed in a rocker. The vessel was heated to 200° C. internal temperature and maintained at that temperature for 5 hours with agitation while the pressure increased to a maximum of 1750 psig. The final pressure at elevated temperature was 1500 psig and at ambient temperature was 600 psig (indicating that hydrogen was consumed by the reaction.) This procedure yielded 59% of the desired gamma-mercaptopropyltriethoxysilane.
