METHOD OF PRODUCING ALKOXYSILANES Russian patent published in 2011 - IPC C07F7/04 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing alkoxysilanes of general formula Si(OR)₄, where R is an alkyl group. Disclosed is a method of producing alkoxysilanes by reacting aliphatic asymmetrical ethers of general formula R₁OR₂, where R₁=butyl, iso-butyl, tert-butyl, tert-amyl and R₂=methyl, ethyl, with finely dispersed silicon metal in gas-vapour phase in a closed reactor at temperature 200-270°C in the presence of copper monochloride as a catalyst, taken in amount of 10-20% of the weight of silicon metal.

EFFECT: improved method of producing alkoxy silanes, which enables to replace chlorosilanes and alcohols with aliphatic ethers, as well as increasing output of alkoxysilanes and purity of the end product.
