FIELD: organic chemistry, chemical technology. ^ SUBSTANCE: invention relates to a method for synthesis of alkoxysilanes. Invention describes a method for synthesis of alkoxysilanes of the general formula: R'nSi(OR)m wherein n = 0-3; m = 1-4 and n + m = 4. Method involves reaction of chlorosilanes of the general formula: R'nSiClm wherein R' means hydrogen atom (H), CH3, C2H4, C2H or C6H6 with alcohols of the general formula: ROH wherein R means (C2-C8)-alkyl or (C2-C8)-aryl. Chlorosilane solution in an inert volatile nonpolar solvent is added to boiling alcohol solution in the same solvent at temperature 75-95°C, solvent is distilled off and evolving dry hydrogen chloride is captured. Method provides increasing yield, simplified process and decreasing time during the reaction carrying out. ^ EFFECT: improved method of synthesis. ^ 6 cl, 1 tbl, 11 ex |
