Complexing agent-modified trimetal cyanide catalyst |
| abstract |
Metal [hexacyanocobaltate, cobalthexanitrite nitroferricyanide] complexes are useful alkylene oxide polymerization catalysts. The metal is any that forms a precipitate with the hexacyanocobaltate, cobalthexanitrite and nitroferricyanide groups. These catalysts are made from less expensive raw materials than the common zinc hexacyanocobaltate catalysts, and provide short induction periods and many cases more controlled exotherms. In addition, the metal [hexacyanocobaltate, cobalthexanitrite nitroferricyanide] catalysts often provide poly(propylene oxide) polymers having very low unsaturations, even when the catalyst is complexed with a complexing agent such as glyme. |
