A process for removing acidic impurities from alkoxysilanes obtained from halogenosilanes and alcohols which inevitable contain small amounts of acidic impurities is described. In the process, at least one member selected from alkali metal salts of alcohols and amines having a great steric hindrance as having a bulky substituent is added to the alkoxysilane for a time sufficient to neutralize the acidic impurities and the mixture is purified by distillation to obtain a substantially acidic impurity-free alkoxysilane.
