| titleOfInvention | Double metal cyanide complex catalyst for ring-opening polymerization of alkylene oxide and method for producing the same |
| abstract | (57) To provide a double metal cyanide complex catalyst catalyst for alkylene oxide ring-opening polymerization and capable of producing a polyether polyol having a low degree of unsaturation with high catalytic activity, and a method for producing the same. An organic ligand, a metal salt, and a transition metal cyanide compound are mixed, and a precipitated solid product is separated from the obtained mixed solution, and then the solid product is washed with water to obtain an organic distribution. Heat contact treatment with an aqueous solution containing a ligand and a metal salt, A method for producing a double metal cyanide complex catalyst for alkylene oxide ring-opening polymerization, wherein a solid is separated from a slurry; and a double metal cyanide complex catalyst for alkylene oxide ring-opening polymerization obtained by the production method. |
