发明名称 PROCESS FOR PREPARING ORGANO(POLY)SILOXANES
摘要 A process for preparing organo(poly)siloxanes of the formula R1R2Si(OSiR2)m(OSiR2)nOH which comprises reacting a hexaorganocyclotrisiloxane of the formula (R2SiO)3 with a sil(ox)anol of the formula R1R2Si(OSiR2)mOH in the presence of a catalyst which contains fluoride ions, in which R is the same or different and represents a monovalent, optionally substituted hydrocarbon radical, R1 represents a hydrogen atom or a monovalent, optionally substituted hydrocarbon radical, m is 0 or an integer of at least 1 and n is an integer of at least 3. An alkali metal fluoride or an alkali metal fluoride bonded to a support material is preferably used as the catalyst in the process of this invention.
