Abstract
The present invention relates to method for producing monosilane and tetraalkoxysilane comprising subjecting alkoxysilane represented by formula (1)HSi(OR)  (1)wherein R represents alkyl group having 1 to 6 carbon atoms and n represents an integer of from 1 to 3, to dismutation reaction in a gaseous phase in the presence of a catalyst containing an alkali metal fluoride and a catalyst activator. The method can solve problems in a method for producing monosilane and tetraalkoxysilane by dismutation reaction of alkoxysilane in a liquid phase: i.e. problems such that separation from the solvent is difficult and that the reaction is too slow and not suitable for industrial production.
