| titleOfInvention | Double metal cyanide complex catalyst and method for producing the same |
| abstract | (57) [Problem] To provide a composite metal capable of shortening the induction period until the start of the reaction without increasing the amount of the catalyst added when ring-opening polymerization of alkylene oxide using the composite metal cyanide complex catalyst A cyanide complex catalyst is provided. In an aqueous medium, a transition metal compound whose transition metal is cobalt and a cyanide transition metal compound whose transition metal is trivalent iron, a metal halide salt, and an organic ligand are reacted. A composite metal cyanide complex catalyst in which the number of cyanoiron (III) ions is 0.02 to 0.95 when the total number of cyanocobaltate ions and cyanoiron (III) ions is 1. To manufacture. |
