Abstract
A method of preparing an alkoxy-functional organosilicon compound is provided. The method comprises reacting (A) an initial organosilicon compound and (B) an alcohol component in the presence of (C) a catalyst, thereby preparing the alkoxy-functional organosilicon compound. The initial organosilicon compound (A) comprises at least one alkoxysilyl group. The alcohol component (B) comprises an organic alcohol. The catalyst (C) comprises (C1) an ammonium carboxylate compound or (C2) a titanate compound. A reaction product comprising an alkoxy-functional organosilicon compound prepared in accordance with the method, and a composition comprising the reaction product, are also provided. The alkoxy-functional organosilicon compound, and the reaction product and composition comprising the same, are prepared in increased purity under functional group-tolerant conditions.
