Abstract: An improved catalyzed reaction of silicon metal with alcohol is provided for the formation of alkoxysilanes, particularly trialkoxysilanes. The Direct Synthesis reaction of silicon metal and alcohol employs a catalytically effective amount of a copper-aluminum alloy as a catalyst precursor and further benefits from an effective catalyst-promoting amount of a catalyst promoter.
