Preparation of sulfide chain-bearing organosilicon compounds

By reacting a halogenoalkyl group-bearing organosilicon compound and optionally sulfur with an aqueous solution or water dispersion of an ammonium or alkali metal polysulfide or a hydrate thereof in the presence of a phase transfer catalyst, a sulfide chain-bearing organosilicon compound having the average compositional formula (2): [in-line-formulae](R1O)(3-p)(R2)pSi—R3—S—R3—Si(OR1)(3-p)(R2)p ??(2) [/in-line-formulae] wherein m has an average value of 2≦m≦6 is obtained in high yields and at a low cost with minimized formation of a monosulfide-bearing organosilicon compound.

Process for preparing organosilanes

Preparation of organosilane compound (I) comprises reaction of (halo-organo) alkoxysilane compound (II) with sulfurizing agent (alkali hydrogensulfide, metal sulfide and/or metal polysulfide) and optionally in addition with sulfur or hydrogen sulfide in alcohol. Preparation of organosilane compound (I) of formula (Si (R) 2(R1O)(R2)-) nX m comprises reaction of (halo-organo)alkoxysilane compound (II) of formula (Si (R) 2(R1O)(R2)-Hal) with sulfurizing agent (alkali hydrogensulfide (3 wt.%), metal sulfide (Me 2S) and/or metal polysulfide (Me 2S g) (10 wt.%)) and optionally in addition with sulfur or hydrogen sulfide in alcohol.

Provided that when n is 2 and m with an average sulfur chain length of 1.5-4.5, then X is S and when n is 1 and m is 1, then X is SH.

Process for the preparation of (mercaptoorganyl)-alkoxysilanen

Production of mercaptoorganyl alkoxysilanes comprises reacting an alkali metal hydrogen sulfide with a mixture of haloorganyl alkoxysilane and haloorganyl halosilane in an alcohol under pressure in a sealed vessel in the absence of oxygen.
