METHOD FOR PREPARING 3-CHLOROPROPYLSILANE Russian patent published in 2008 - IPC C07F7/12 

FIELD: organic chemistry, chemical technology.

SUBSTANCE: invention relates to methods for synthesis of (-γ)-propylsilanes substituted at position 3. Invention proposes initial charging a platinum-containing catalyst and 10-30 wt.-% of reaction mass from previous step or vat residues after isolation of the end product from previous step into reactor. Then the mixture is heated to temperature 65°C and silane hydride and allyl chloride are dosed maintaining the mole ratio silane hydride and allyl chloride in the reaction mass = (1.0-1.2):1. Invention provides development of method allowing significant decreasing consumption of catalyst, declining formation of by-side products and enhancing the effectiveness of technological process.

EFFECT: improved method of synthesis.
