Reaction Conditions

Reaction Steps

Into a clean, dry 300 cubic centimeter high pressure reactor were added 150 grams (0.60 moles) of beta-triethoxysilylthiopropionamide product (Example II pilot plant lot containing 5% beta-cyanoethyltriethoxysilane starting material) and 2.5 weight percent of cobalt trisulfide. The reactor was sealed, initially pressurized to 600 psig with hydrogen and placed in a rocker. The vessel was heated to 195° C. internal temperature which raised the hydrogen pressure to 1100 psig. Heating was maintained for 8 hours with agitation. Hydrogen was continuously fed into the reactor to maintain the hydrogen pressure at about 1000 psig. The pressure never exceeded 1100 psig. The pressure at the end of the reaction was 575 psig. The reaction produced the desired gamma-mercaptopropyltriethoxysilane.
