Method for the production of double metal cyanide catalysts |
| abstract |
The present invention relates to a process for producing a double metal cyanide catalyst (DMC) comprising the reaction of an aqueous solution of a cyanide-free metal salt, an aqueous solution of a metal cyanide salt, an organic complex ligand and a complex-forming component with formation of a dispersion, the reaction using a mixing nozzle takes place and the process temperature of the dispersion during the reaction is between 26 ° C and 49 ° C. The invention furthermore relates to double metal cyanide catalysts (DMC) obtainable by the process according to the invention and the use of the DMC catalysts for the production of polyoxyalkylene polyols. |
