    • 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.
    • 公开了一种金属氰化物络合物催化剂及其制备和应用。 该催化剂的配方为M1a [M2(CN)bL1c] d(X)m(L2)n.xSu.yL3.zH2O,其制备方法包括:(A)调节L3,M3e的混合溶液I' [M2(CN)bL1c] f,去离子水I,醇和/或醚溶剂至小于7.0,并将其加入M1(X)g盐,Su或Su前体的混合溶液II' 电离水II,在20〜120℃下搅拌反应0.5〜200小时,分离并干燥得到固体产物; 和(B)将固体重复分散在含有L2的无水有机溶剂中以形成浆料,蒸馏,分离和干燥,得到金属氰化物配合物催化剂。 该催化剂可用于通过环氧化物的均聚或环氧化物与二氧化碳或酸酐的共聚制备聚醚,聚碳酸酯和聚酯。
