| description | There is provided a process for the production of sulfur containing organosilicon compounds of the formula (I) Z - Alk - Sx - Alk - Z, where Z is the grouping: +TR in which R1 is an alkyl group having 1 to 5 carbon atoms, a cycloalkyl group with 5 to 8 carbon atoms, the benzyl group, phenyl or phenyl substituted with at least one methyl, ethyl or chloro group, R2 is alkoxy of 1 to 4 carbon atoms, methoxyethoxy, cycloalkoxy with 5 to 8 carbon atoms, phenoxy or benzyloxy, R3 and R4 are alkyl of 1 to 3 carbon atoms or hydrogen, Alk is divalent saturated hydrocarbon group having 1 to 5 carbon atoms or such a group interrupted by -O-, -S- or -NH- and x is a number from 2.0 to 6.0 comprising reacting an alkali metal alcoholate, preferably in alcoholic solution with a compound of the formula (II) Z - Alk - Hal, where Hal is chlorine, bromine or iodine with a hydrosulfide of the formula (III) MeSH, in which Me is ammonium, an alkali metal atom or an equivalent of an alkaline earth metal or zinc and with sulfur, preferably in the presence of at least one organic solvent, separating from the halide formed, and removing the organic solvent. |
