摘要:
An improved method for synthesizing a double metal cyanide (DMC) catalyst combines and sonicates aqueous and non-aqueous solutions of a first metal salt, such as Zn(OAc)2, of a second metal salt, such as CoCl2, and of an alkali metal cyanide, such as NaCN, to synthesize the DMC catalyst, Zn3[Co(CN)6]2. An improved method of producing a polyether polyol uses the DMC catalyst to produce the polyol.
