METHOD FOR SYNTHESIS OF MERCAPTOORGANYL(ALKOXYSILANES) Russian patent published in 2010 - IPC C07F7/18 C07C319/06 

Abstract RU 2387659 C2

FIELD: chemistry.

SUBSTANCE: engineering problem is to design a method for synthesis of mercaptoorganyl(alkoxysilanes) through reductive splitting of bis(alkoxysilylorganyl)polysulphides, which avoids additional use of water, alcohols and hydrogen sulphide and ensures high conversion. Proposed is a method for synthesis of mercaptoorganyl(alkoxysilanes) through hydrogenation of bis(alkoxysilyl-organyl)polysulphides at temperature below 190°C and pressure less than 100 bars under the effect of hydrogen in the presence of a transition metal-based catalyst without addition of water, alcohol or H2S.

EFFECT: proposed method can be realised in periodic and in continuous modes and ensures high conversion.
