Reaction Steps
Utilizing a 15 gallon high pressure stainless steel system, 80 pounds of beta-cyanoethyltriethoxysilane and 8 pounds of diethylamine were added initially. With a diptube, 12 pounds of hydrogen sulfide was charged into the reactor while cooling was maintained. The reactor was then heated to 60° C. with stirring for 6 hours. The residual hydrogen sulfide (80 psig) was carefully vented into a caustic scrubber and the product thioamide (94 pounds) was collected. The product, analyzed by InfraRed Spectroscopy, contained 5% unreacted nitrile.
