    • Process for preparing double metal cyanide catalysts of the general formula (I) M2a[M1(CN)rXt]b   (I) where M2 is preferably Co(III) or Fe(III), and M1 is preferably Zn(II), X is a group other than cyanide which forms a coordinate bond to M1 and is selected from the group consisting of carbonyl, cyanate, isocyanate, nitrile, thiocyanate and nitrosyl, a, b, r, t are integers which are selected so that the compound is electrically neutral, by reacting a) a cyanometallic acid of the general formula (II) Hw[M1(CN)r(X)t] where M1 and X are as defined above, r and t are as defined above and w is selected so that the compound is electrically neutral, with b) a readily protolyzable metal compound (IIIa) M2Rw and/or (IIIb) M2RuYv, where M2 is as defined above, the groups R are identical or different and are each the anion of a very weak protic acid having a pKa of ≧20, and Y is the anion of an inorganic mineral acid or a moderately strong to strong organic acid having a pKa of from −10 to +10, w corresponds to the valence of M2, u+v corresponds to the valence of M2, with u and v each being at least 1, with the reaction being carried out in a nonaqueous, aprotic solvent.
