Abstract

The present invention relates to a process for preparing a polyetherol which comprises reacting at least one alkylene oxide with at least one starter compound in the presence of a catalyst of the formula I:M1p[M2qOn(OH)2(3-n)]x,  (I)and to the polyetherols prepared by such a process and to their use for the synthesis of polyurethanes, as fuel additive or as surfactant.
