Abstract: The present invention relates to a process for the production of polyether alcohols by catalytic addition of alkylene oxides to H-functional initiators using amines as catalysts, wherein the addition of the amines to the reaction mixture is effected prior to or at the commencement of the chemical addition of the alkylene oxides and also at least once during the reaction, said additional addition of the catalyst being carried out at the point of the reaction at which there is an increased occurrence of side reactions and/or when the alkylene oxides undergo a change in the polyether chain.
