Abstract: PROBLEM TO BE SOLVED: To provide a method for producing an alkoxysilane containing halides only a little. SOLUTION: The method of this invention is to bring the first mixture containing an alkoxysilane of the formula: RaHbSi(OR1)4-a-b [Rs are each a 1-20C (substituted) hydrocarbon; R1s are each 1-4C hydrocarbon; (a) is 0-3; (b) is 0-3; (a)+(b) is 0-3] and residual halides into contact with the second mixture containing 1.5-15 mol (1-4C) alkyl alcohol and 0.1-5 mol orthoformate of the formula: HC(OR1)3 respectively based on 1 mol of residual halides in order to form the final mixture containing the newly produced alkoxysilane and low-boiling chemical species and then by separating the low-boiling chemical species from the alkoxysilane.
