  • Patent number: 9469722
    Abstract: A metal cyanide complex catalyst and its preparation and application are disclosed. The formula of this catalyst is M1a[M2(CN)bL1c]d(X)m(L2)n.xSu.yL3.zH2O and its preparation method comprises: (A) adjusting pH of a mixed solution I? of L3, M3e[M2(CN)bL1c]f, de-ionized water I, alcohol and/or ether solvent to less than 7.0, and adding it into a mixed solution II? of M1(X)g salt, Su or Su precursor, de-ionized water II, stirring for reaction under 20° C.-120° C. for 0.5-200 hours, separating and drying to obtain a solid product; and (B) repeatedly dispersing the solid into an anhydrous organic solvent containing L2 to form a slurry, distilling, separating and drying to obtain the metal cyanide complex catalyst. The catalyst is useful in preparing polyethers, polycarbonates and polyesters by homopolymerization of epoxides, or copolymerization of epoxides with carbon dioxide or anhydrides.
