Method of manufacturing of oligo(4-(2-organo-organooxysilylalkyl)cyclohexane-1,2-diyl)bis-oligosulfides

摘要

The invention relates to a method of manufacturing oligo(4-(2-organo-organooxysilylalkyl)cyclohexane-1,2-diyl)bis-oligosu lfides from products of industrial-scale synthesis of 4-(2-organo-organooxysilylalkyl)-1-cyclohexene, without the use of catalysts and at normal pressure. The products produced are used as silane binders and adhesives, and as strengthening additives in silicate filled rubber mixtures. According to the invention, an organosilane of general formula <IMAGE> I containing an organochlorosilane of general formula <IMAGE> II where R and R2 each independently represent an C1-6 alkyl group; R1 represents an alkyl, cycloalkyl, or aryl group; n=1 to 3; and m=1 or 2; with the molar ratio of I to II being in the range 1000:1 to 10:1, is reacted directly with sulfur, in a molar ratio of R:sulfur (and/or hydrogen sulfide) of 1:1 to 1:5, at temperatures >150 DEG C.
