Patent ID: 7396951

Claim:
A process for production of trialkoxyhalosilanes, which comprises reacting a tetrahalosilane represented by Formula 1 with a tetraalkoxysilane represented by Formula 2 in the mixture of an alcohol composed of the same alkoxy group as that of the tetraalkoxysilane to yield a trialkoxyhalosilane represented by Formula 3, wherein the alcohol is used in an amount of 10-50% by mol based on a total amount of Si in the tetrahalosilane and the tetraalkoxysilane: SiX4 [Formula 1] (where X denotes halogen) Si(OR 1 ) 4 [Formula 2] (where R 1 denotes a hydrocarbon group having 1-6 carbon atoms) XSi(OR 1 ) 3 [Formula 3] (where X denotes halogen; and R 1 a hydrocarbon group having 1-6 carbon atoms).
