摘要： Alkoxysilanes containing low levels of chlorine compounds are prepared by stepwise etherification of chlorosilanes with alcohols in liquid phase and removal of the resulting hydrogen chloride by reacting the alkoxysilane obtained, which still contains a small amount of chlorine compound, with a metal alkoxide in an amount which corresponds to a small stoichiometric excess based on the proportion of chlorine compound, and freeing the reaction product from the resulting salt.
