    摘要: Alkoxylation products are prepared by reacting compounds having active hydrogen atoms with C.sub.2 -C.sub.4 -alkylene oxides in the presence of a mixed hydroxide built up of polycations and modified with additives and having the general formula I or II �M(II).sub.1-x M(III).sub.x (OH).sub.2 !A.sub.x/n .multidot.m L(I) �LiAl.sub.2 (OH).sub.6 !A.sub.1/n .multidot.m L (II) where M(II) is at least one divalent metal ion, M(III) is at least one trivalent metal ion, A is at least one inorganic anion and L is an organic solvent or water, n is the valence of the inorganic anion A or in the case of a plurality of anions A is their mean valence and x can assume a value of from 0.1 to 0.5 and m can assume a value of from 0 to 10, as alkoxylation catalyst, wherein the mixed hydroxide contains additives.
