PROCESS FOR THE PREPARATION OF ORGANOSILANES

摘要

The invention relates to a process for the preparation or organosilanes of the general formula I (see formula I) by reacting a (haloorganyl)alkoxysilane of the formula II (see formula II) with a sulphurization reagent selected from the group consisting of alkali metal hydrogen sulphide, alkali metal sulphide Me2S, alkali metal polysulphide Me2S g and any desired combinations thereof, and optionally additionally with sulphur and/or with H2S, in an alcohol, the Me2S or Me2S g containing more than 10% by weight of water and the alkali metal hydrogen sulphide containing more than 3% by weight of water.
