    摘要: A method for purifying alkoxysilane with the general formula, R.sub.m Si(OR.sup.1).sub.4-m. The method significantly lowers the level of non-hydrolyzable chlorine-based impurities, as well as the level of hydrolyzable chlorine-based impurities. The method comprises: (i) heating the alkoxysilane in the presence of a treating agent selected from a group which consists of acid clays and metal halides; (ii) contacting the alkoxysilane with a neutralization agent; and (iii) separating the alkoxysilane from the unused neutralization agent and by-products of neutralization.
