SILANOL COMPOUND, COMPOSITION, AND METHOD FOR PRODUCING SILANOL COMPOUND

摘要

The purpose of the present invention is to provide silanol compounds that can be used as raw materials of siloxane compounds and the like, and a composition of the silanol compounds, as well as to provide a production method that makes it possible to produce silanol compounds at excellent yield. A composition containing from 10 mass% to less than 100 mass% of silanol compounds represented by formulas (A)-(C) can be prepared by devising to produce silanol compounds under water-free conditions, to produce silanol compounds in a solvent having the effect of suppressing the condensation of silanol compounds, and to perform other such processes, the composition being able to be used as a raw material or the like of siloxane compounds because the silanol compounds can be stably present in the resulting composition. (In formulas (B) and (C), each R1 independently represents a C 1-5 hydrocarbon group.)
