Procedure

24.3 grams of potassium thiocyanate were dissolved in 900 ml. of n-butanol and the solution heated to boiling. Then there were added dropwise in about 30 minutes 81.3 grams of 3-chloropropyl tri-n-butoxy silane. After a further 20 hours of boiling at reflux temperature the precipitated potassium chloride was separated off with a Seitz filter. The solvent was distilled off from the filtrate and the 3-thiocyanatopropyl tri-n-butoxy silane distilled in vacuo. B.P. 0.1 128°-129° C., yield 85% based on the weight of the 3-chloropropyl tri-n-butoxy silane.
