Preparation of sulfur-containing organosilicon compounds using a buffered phase transfer catalysis process

摘要

The present invention of the formula M ₂ S _n or MHS of the sulfide compound (A) [where, H is hydrogen, M is ammonium or an alkali metal and, n is 1 to 8. The number of] the phase transitions on the containing catalyst and buffer aqueous silane compounds of the formula (RO) _3-m R _m Si-Alk-X in the presence (B) [wherein, X is Cl, Br or I, m is an integer from 0 to 2; and any sulfur (C) comprising the reaction of the formula _{(RO) 3-m R m} Si-Alk-S n -Alk-SiR m (OR) a sulfur-containing organosilicon compounds of the _3-m [wherein, R is independently a group having 1 to 12 carbon atoms of a monovalent hydrocarbon group, Alk is a divalent hydrocarbon group having 1 to 18 carbon atoms of 2, m is an integer from 0 to 2, n is a number of 1 to 8] relates to a process for preparing. The present invention is characterized in that the buffer solution was added to the aqueous phase to minimize the gelling of the sulfur containing organosilicon compound or prevented. The invention also teaches a method for preparing a sulfur-containing organosilicon compound by adjusting the pH of the aqueous phase. ; Organosilicon, sulfide, sulfur, a buffer solution, the aqueous phase
