METHOD FOR PREPARING METAL CYANIDE CATALYSTS USING INSOLUBLE METAL SALTS |
摘要 |
Metal cyanide catalyst dispersions in initiator compounds and/or polyethers are prepared by reacting an acidic metal cyanide compound with an insoluble metal salt in a medium that is a solvent for the acidic metal cyanide compound but not the metal salt. The resulting catalyst slurry may be combined with an initiator and stripping 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 not necessary to use a separate organic complexing agent in the preparation. |
