Abstract: FIELD: organic chemistry, chemical technology. 
     SUBSTANCE: invention describes a method for preparing alkoxysilanes of the formula: SiH(OR) 4-n  wherein n = 0, 1; R means alkyl group. Method involves interaction of ground silicon with alcohol in the presence of copper-containing catalyst in high-boiling solvent medium at elevated temperature to prepare the end product and formation of soluble products of by-side reactions and small-dispersed slime presenting with silicon and catalyst in reaction mass as suspension. In the process of synthesis part of suspension is removed periodically and then catalyst and silicon are added in the amount equal to amount consumed to moment of suspension remove, and solvent in amount equal to its removed part. Removed part of suspension is settled for precipitation of unreacted silicon that is recovered to the process and remained part of suspension is fed to regeneration of solvent. Proposed method for preparing alkoxysilanes allows increasing production yield from unit of reaction equipment unit, to enhanced the yield of the end product due to reducing intensity of by-side reactions (as no slime is accumulated in reactor) and to exclude zones with elevated concentration of alcohol due to its high conversion.
