Title:
METHOD FOR PREPARING TRIALKOXYSILANE
Document Type and Number:
WIPO Patent Application WO/2013/035956
Kind Code:
A1
Abstract:
The present invention relates to a method for preparing SiH(OR)3-type trialkoxysilane (wherein, R is a C1-C3 methyl, ethyl, propyl or isopropyl group), and more specifically, the method comprises the steps of: preventing the oxidation of a silicon surface by pulverizing raw silicon material in a solvent environment without contact with the air so that the initial induction period of the direct synthesis of trialkoxysilane is dramatically reduced; and removing impurities from a reaction environment by continuously selecting a part of the solvent through a membrane filter provided in a reactor body.
