| abstract |
The invention relates to a process for the preparation of organosilanes of the general formula I where X = S if n = 2, and X = SH if n = 1, by reacting (haloorganyl) alkoxysilane of the formula II, with a sulfurizing reagent selected from the group of alkali hydrogen sulfide, alkali metal sulfide Me 2 S, alkali metal polysulfide Me 2 S g and any combinations thereof, and optionally additionally with sulfur and / or with H 2 S in alcohol, the Me 2 S or Me 2 S g more than 10 wt .-% water and the alkali metal hydrogen sulphide contains more than 3 wt .-% water. |
