ORGANOSILICON COMPOUNDS, PROCESSES OF PRODUCTION THEREOF, AND RUBBER COMPOUNDS CONTAINING THE SAME Russian patent published in 2006 - IPC C07F7/18 C07F7/10 C07F7/08 

FIELD: organosilicon compounds in rubber industry.

SUBSTANCE: invention provides organosilicon compounds of formula I and/or II:

, where R represents methyl or ethyl group; R^', identical or different, branched or linear C₉-C₃₀-alkyl or C₉-C₃₀-alkenyl, aryl, arylalkyl, branched or linear C₂-C₃₀-alkyl ether group, branched or linear C₂-C₃₀-alkyl polyether group, R^''' ₃Si group, wherein R^''' represents branched or linear alkyl or alkenyl, arylalkyl, or aryl; R^' represents branched or linear, saturated or unsaturated aliphatic, aromatic, or mixed aliphatic/aromatic group with double bond; X is O(C=O)-R^''' when n=1 and m=1, SH when n=1 and m=1, S when n=2 and m=1 to 10 and mixture thereof, S(C=O)-R^''' when n=1 and m=1, or H when n=1 and m=1; which are prepared by reaction of silanes of general formula III:

with alcohols of general formula R^'-OH, which reaction also produces R-OH. The latter is continuously separated from reaction mixture.

EFFECT: extended resource of curing agents in rubber vulcanization processes.
