  • Method for producing double metal cyanide catalysts
    Patent number: 11976165
    Abstract: The present invention relates to a method for producing a double metal cyanide (DMC) catalyst, 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, optionally a complex-forming component to form a dispersion, the dispersion being produced using a mixing nozzle and a peroxide. The invention further relates to double metal cyanide (DMC) catalysts obtainable by means of the method according to the invention and to the use of DMC catalysts to produce polyoxyalkylene polyols.
