- PRODUCTION METHOD FOR ALKOXYSILANES
-
Provided is a method for efficiently producing alkoxysilanes that are useful as various functional chemicals. In order to produce alkoxysilanes efficiently, an ethoxy- or methoxysilane and an alcohol are caused to react using, as a catalyst, for instance an inorganic solid acid having a regular-pore and/or layered structure. Zeolites, montmorillonites or the like can be used as the inorganic solid acid. When a zeolite is used as the catalyst, the silica/alumina ratio of the zeolite ranges preferably from 5 to 1000. The reaction can be promoted through irradiation of microwaves.

PROBLEM TO BE SOLVED: alkylalkoxysilane compounds useful as a chemical product having various functions, and [...] or obtained from the same and to provide a manufacturing method thereof. SOLUTION: the alkylalkoxysilane, or a methoxy group and an ethoxy group, an alkyl group oxystyrene, thioalkyl group, on the same silicon atom or an alkyl group halogenopyridine structure having, for example, a plurality of silane-based or methoxysalicylic naphtholsulfonic, regular porous structure having a solid acid and alcohol in the presence of catalyst inorg. by reaction can be produced. Furthermore, water and the like of [...] alkylalkoxysilane obtained by reaction, is allowed to coexist with acid or the like can be performed efficiently.
