摘要

When a CuCl/Si mixture was pretreated at 200-240 degrees C in a N-2 atmosphere, trimethoxysilane was predominantly formed in the direct reaction of silicon with methanol. When the pretreatment temperatures were raised to 260-340 degrees C, tetramethoxysilane was favorably formed. The CuxSiyClz species catalyzed the reaction between silicon and methanol to trimethoxysilane. Chlorination of the spent CuCl/Si mixture promoted the reaction between silicon and methanol to form both trimethoxysilane and tetramethoxysilane due to the recovery of the CuCl phase and the exposure of the metallic Cu-0 phase. When Cu2O, CuO, and Cu-0 were used as the catalysts, tetramethoxysilane was formed as the main product.
