Abstract

The liquid-phase reactions of silicon, methanol and ethylene in an autoclave gave ethylmethoxysilanes (HSi(C₂H₅)(OCH₃)₂ and Si(C₂H₅)(OCH₃)₃) besides HSi(OCH₃)₃ and Si(OCH₃)₄. The reaction conditions for obtaining a high selectivity for the ethylmethoxysilanes were examined. With the use of a high pressure of ethylene and a small amount of methanol in toluene as a solvent at 433 K, ethylmethoxysilanes were obtained in 26% selectivity at silicon conversion of 59%. The direct reaction of silicon with ethanol and ethylene gave HSi(C₂H₅)(OC₂H₅)₂ and Si(C₂H₅)(OC₂H₅)₃.
