PURPOSE:To obtain a monosilane in high yield, with each separation of the catalyst from the reaction product, by carrying out the disproportionation of an alkoxysilane using cobalt, nickel or metal of platinum group or their compound as a catalyst. CONSTITUTION:A monosilane can be produced by the disproportionation of the alkoxysilane of formula (R is 1-6C alkyl; n is 1, 2 or 3) in the presence of a catalyst consisting of cobalt, nickel platinum-group metal or their compound. The object of the invention can be achieved by using >=0.01wt% catalyst based on alkoxysilane, however, the catalyst is used usually in an amount of 0.1-50wt%. The reaction can be carried out batchwise or continuously. The reaction type can be selected freely according to the form of the catalyst since there is no restriction in the material of the apparatus.
