Abstract
In a process for producing trialkoxysilanes by reaction of a metallic silicon and an alcohol having 1 to 4 carbon atoms, the reaction is effected (1) using as the metallic silicon one containing 0.30 to 0.37% by weight of aluminum, (2) using as the catalyst cuprous chloride prepared by a wet process, and (3) allowing aluminum and/or an aluminum compound to coexist, thereby securing a high conversion rate of metallic silicon, and accordingly decreasing the amount of unreacted metallic silicon and suppressing discharge of industrial wastes with eliminating environmental problems.
