Versuchsvorschrift
Into a clean, dry 300 cubic centimeter high pressure reactor were added 58 grams (0.23 moles) of beta-triethoxysilylthiopropionamide product (Example II pilot plant lot containing 5% beta-cyanoethyltriethoxysilane starting material), 1.45 grams (2.5 weight percent) of rhenium heptasulfide catalyst (Re2S7.2H2O), and 12 grams ethanol rinse. The reactor was sealed, initially pressurized to 800 psig with hydrogen, and placed in a rocker. The vessel was heated with agitation for 4 hours to a maximum pressure of 1000 psig. After cooling to ambient temperature, the pressure was 0 psig, indicating that hydrogen was consumed by the reaction. The reaction had produced gamma-mercaptopropyltriethoxysilane.
