METHOD FOR PREPARING METAL CYANIDE CATALYSTS USING ZERO VALENT METALS |
摘要 |
Metal cyanide catalyst dispersions in initiator compounds and/or polyether are prepared by reacting an acidic metal cyanide compound a zero valent metal in a medium that is a solvent for the acidic metal cyanide compound. The resulting catalyst slurry may be combined with an initiator and/or polyether and stripped to form a catalyst/initiator or catalyst/polyether slurry. Using this method, an active alkylene oxide polymerization catalyst is prepared, and the preparation method is greatly simplified. Further, it is necessary to use a separate organic complexing agent in the preparation. |
