Beschreibung
Zusammenfassung:	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.
