Abstract

Disclosed is an improved process for the slurry phase Direct Synthesis of trialkoxysilanes which comprises the activation of copper catalyst and silicon with a reducing agent such as hydrogen gas, carbon monoxide or monosilane. Such activation affords high, stable reaction rates and selectivities and high silicon overall conversion especially in alkylated benzene solvents.
