A process for trialkoxysilane/tetraalkoxysilane mixtures from silicon metal and alcohol

摘要

A process for producing controlled trialkoxysilane/tetraalkoxysilane mixtures by the direct reation of silicon metal with an alcohol in the presence of a catalytically effective amount of a copper catalyst and mixed solvents, wherein at least one solvent is inert and does not degrade under the reaction conditions and at least one other solvent promotes the reaction between trialkoxysilanes and alcohol.
