    • The invention relates to a method for producing polyether alcohols by attaching alkylene oxides to H-functional initial substances, using multimetal cyanide compounds as catalysts, characterized by the fact that the multimetal cyanide compound is produced by a method comprising the following steps: a) a metal salt solution is added to a cyano-metal solution at a specific stirring rate e ranging between 0.05 and 10 W/l, preferably between 0.4 and 4W/l, and at a temperature ranging between 0 °C and 100 °C, preferably between 20 °C and 60 °C, during an addition time lasting between 5 and 120 minutes; b) the specific stirring rate e is reduced to between 0.03 and 0.8 W/l while a surface-active substance is added; c) the solution is heated to a maximum temperature of 100 °C, preferably between 55 °C and 75 °C, while being stirred at a specific stirring rate e ranging between 0.03 and 0.8 W/l; d) an additional amount of the metal salt solution is added and stirred at a specific stirring rate e of 0.03 to 0.8 W/l; e) the solid substance is dispersed, e.g. by stirring at an increased specific stirring rate e of > 0.7 W/l or by incorporating a transfer pump circuit comprising a corresponding pump or a dissolver, when the conductivity begins dropping; f) stirring at the specific stirring rate e used in step e) until the conductivity or the pH value remains stable; g) the multimetal cyanide compound is isolated and washed with water; and h) the catalyst is optionally dried.
