Abstract: The present invention relates to a process for reacting epoxides with an initiator compound in the presence of a double metal cyanide compound as a catalyst, said process having a shortened induction period, and the double metal cyanide compound being activated by adding the epoxide to a mixture of double metal cyanide compound and initiator compound at an internal reactor pressure of less than 1 bar, and also to the polyethers themselves obtainable by such a process.

Abstract: The invention relates to a process for preparing polyether alcohols by addition of alkylene oxides onto H-functional starter substances using multimetal cyanide compounds as catalysts, wherein the multimetal cyanide compound is prepared by a process comprising the steps: a) adding a metal salt solution to a cyanometalate solution at a specific stirring power epsilon in the range from 0.05 to 10 W/l, preferably from 0.4 to 4 W/l, a temperature in the range from 0° C. to 100° C., preferably from 20° C. to 60° C., and an addition time of from 5 to 120 minutes, b) reducing the specific stirring power epsilon to a value in the range from 0.03 to 0.8 W/l and at the same time adding a surface-active agent, c) heating the solution while stirring at a specific stirring power epsilon of from 0.03 to 0.8 W/l, to a temperature of not more than 100° C., preferably in the range from 55° C. to 75° C., d) adding further metal salt solution while stirring at a specific stirring power epsilon of from 0.03 to 0.8 W/l, e) when the conductivity begins to drop, dispersing the solid, for example by stirring while increasing the specific stirring power epsilon to >0.7 W/l or by installation of a pumped circuit with an appropriate pump or by means of a high-speed stirrer, f) stirring at the specific stirring power epsilon of step e) until the conductivity or the pH remains constant, g) separating off the multimetal cyanide compound and washing it with water and, if desired, h) drying the catalyst.

Abstract: The invention relates to a method for producing polyether alcohols, comprising the following steps: a) reacting a low-molecular alcohol with alkylene oxide in the presence of a basic catalyst in order to form an alkylene oxide addition product having a molecular weight ranging from 200 to 900 g/mol; b) separating the basic catalyst from the product obtained in step a), and; c) reacting the product obtained in step b) with another alkylene oxide in order to produce the desired final product while using at least one DMC catalyst. The inventive method is characterized in that sodium hydroxide is used as the basic catalyst in step a).
