    Abstract: The invention relates to a method for producing polyetherols that involves the reaction of at least one alkylene oxide with at least one starter compound in the presence of at least one double metal cyanide compound to form a polyetherol and the treatment of the obtained polyetherol with steam or with an inert gas and steam. The invention also relates to the polyetherols themselves that can be obtained according to a method of the aforementioned type and to the use of these compounds for synthesizing polyurethanes.

    Abstract: Process for preparing polyether polyols having an end block of ethylene oxide by addition of alkylene oxides onto H-functional starter substances, in which A) a polyether polyol precursor is prepared by means of double metal cyanide (DMC) catalysis in a semicontinuous mode of operation in which previously prepared polyether polyol together with the DMC catalyst are placed in a reactor and H-functional starter substance and propylene oxide are added continuously; B) the polyether polyol precursor from stage A) is reacted with propylene oxide or an ethylene oxide/propylene oxide mixture in the presence of the DMC catalyst in a continuously operating reactor to give a polyether polyol intermediate; C) the intermediate from stage B) is mixed with an alkali metal hydroxide as catalyst and D) reacted with ethylene oxide in a continuously operating reactor to give the final product; E) the catalyst is separated off from the final product obtained in stage D).

    Abstract: Disclosed is a method for producing double metal cyanide complex catalysts of general formula M2a[M1(CN)rXt]b, wherein M2 preferably represents Co(III) or Fe(III) and M1 preferably represents Zn(II), X represents a group that is different from cyanide, forms a coordinate link to M1, and is selected among the group comprising carbonyl, cyanate, isocyanate, nitrile, thiocyanate, and nitrosyl, a, b, r, t represent integers which are selected such that the electroneutrality condition is met. Said double metal cyanide complex catalysts are produced by reacting a) a cyanometallate hydrogen acid of general formula Hw[M1(CN)r(X)t], wherein M1 and X are defined as indicated above, r and t are defined as indicated above, and w is selected such that the electroneutrality condition is met, with b) an easily protolyzable metal compound M2RW and/or M2RuYv, wherein M2 is defined as indicated above, R independently represents the anion of a very weak protonic acid having a pKs value of > 20, Y represents the anion of an inorganic mineral acid or a moderately strong to strong organic acid having a pKs value ranging from -10 to +10, w corresponds to the valence of M2, and u + v corresponds to the valence of M2, u and v amounting at least to 1, respectively. The reaction is carried out in a nonaqueous, aprotonic solvent.
