PURPOSE:To continuously obtain the aimed compound in high yield, by previously heat-treating both metallic silicon and a copper catalyst in hydrogen atmosphere in producing the titled compound by directly reacting the metallic silicon with an alkyl alcohol in the presence of the copper catalyst by a liquid phase method. CONSTITUTION:In providing an alkoxysilane by reacting a metallic silicon with an alkyl alcohol in the presence of a copper catalyst in a reaction medium, the metallic silicon and the copper catalyst are used by previously heat-treating in hydrogen gas atmosphere preferably at 200-300 deg.C, whereby accelerating interaction between the metallic silicon and the copper catalyst to improve production rate of the titled compound and permit continuous operation. In a certain case, an alkali metal alcoholate or alkali metal is further used with the said catalyst as a promoter to maintain the activity of the copper catalyst for a long period, whereby to further improve the yield of the aimed compound and make possible continuous operation for a long period at the same time. |
