Abstract
An improved method for synthesizing a double metal cyanide (DMC) catalyst includes combining a non-aqueous solution of a first metal salt, such as ZnBr, with a non-aqueous solution of a second metal salt, such as CoBr, and with a non-aqueous solution of an alkali metal cyanide, such as NaCN, in a single step to synthesize the DMC catalyst, Zn[Co(CN)].
