An improved process for the production of organosilicon compounds of the formulawhere R is independently a monovalent hydrocarbon of 1 to 12 carbon atoms,Alk is a divalent hydrocarbon of 1 to 18 carbon atoms;m is an integer of 0 to 2, n is a number from 1 to 8 is disclosed. The process comprises:(A) reacting sulfur, a phase transfer catalyst, a sulfide compound having the formula M2Sn or MHS,where H is hydrogen, M is ammonium or an alkali metal, n is the same as above,and water to form an intermediate reaction product;(B) reacting said intermediate reaction product with a silane compound of the formula;where X is Cl, Br or I, and m is the same as above(C) separating the organosilicon compound from the product mixture by adding water or a dilute acidic solution to the product mixture, and phase separating the product mixture into an organic phase containing the organosilicon compound and an aqueous phase. |
