The present invention relates to a process for preparing autocatalytic polyether alcohols by reacting H-functional starter substances containing at least one amino group which is catalytically active in the urethane reaction, in particular a tertiary amino group, and at least one group which is reactive toward alkylene oxides, in particular a primary and/or secondary amino group and/or hydroxyl group, with alkylene oxides, which comprises

Device for producing polyether alcohols

The invention relates to polyether alcohols, to a process for preparing polyether alcohols by reacting alkylene oxides in the presence of a double metal cyanide (DMC) catalyst with at least one saturated OH component which may, if appropriate, have previously been reacted with an alkylene oxide, wherein an antioxidant is added before or during the reaction, and also to the further processing of the polyether alcohols to form polyurethanes.
