  • Alkoxysilanes and oligomeric alkoxysiloxanes by a silicate-acid route
    Patent number: 5183914
    Abstract: The present invention relates to a novel method of preparing alkoxysilanes and oligomeric alkoxysiloxanes. The method comprises reacting a metal silicate with an acid selected from the group consisting of sulfurous acid and acids with a pKa greater than about 2.5 in the presence of an alcohol. The resultant product is then reacted with an alcohol to form the alkoxysilane or oligomeric alkoxysiloxane, depending on the starting silicate. This method is particularly valuable since the reaction conditions are mild and the reactants are readily available.
