ABSTRACT:
This invention is concerned with an improved process for producing trialkoxysilanes comprising (i) an activation step where elemental silicon and a copper catalyst are activated, (ii) a reaction step where an alcohol is contacted with elemental silicon and the copper catalyst to allow it to react with the elemental silicon and (iii) a purification step where reaction product obtained is separated and/or refined, which is characterized in that a halide is introduced into the reaction system and/or mixture in one or more of the above steps (i) to (iii). With the introduction of a halide, the lowering in the selectivity of trialkoxysilanes can be prevented, and the percentage of elemental silicon reacted can be increased. In addition, the trialkoxysilanes contained in the reaction product can be stabilized.
