Abstract
Alkoxysilane composition, which is inhibited from disproportionation reaction that may cause production of monosilanes or reduction in purity of products, contains an alkoxysilane represented by the formula [I] and substantially free from alcohols: EQU H.sub.m R.sub.n Si(OR').sub.4-m-n [I] wherein m is an integer of 1-3, n is an integer of 0-2, m+n.ltoreq.3, R is a C.sub.1 -C.sub.8 alkyl group, and R' is a C.sub.1 -C.sub.4 alkyl group, with a proviso that when there are two or more R or R', R and R' may be the same or different respectively, and at least one compound selected from the group consisting of organic sulfonic acids, sulfuric acid, SO.sub.2, carboxylic acids, carboxylic anhydrides and CO.sub.2.
