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

Abstract RU 2388763 C2

FIELD: chemistry.

SUBSTANCE: invention relates to methods for synthesis of mercaptoorganyl(alkoxysilanes). Proposed is a method for synthesis of mercaptoorganyl(alkoxysilanes) through hydrogenation bis(alkoxysilyl-organyl)polysulphides in a non-alcohol solvent under the effect of hydrogen and in the presence of a transition metal based catalyst without addition of alcohols, H₂S or water. The proposed method can be realised in periodic and in continuous modes and ensures high conversion.

EFFECT: design of 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.
