  • Method for the preparation of polyether alcohols
    Publication number: 20050215831
    Abstract: The invention relates to a process for the work-up of polyether alcohols which have been prepared by base-catalyzed addition of ethylene oxide and propylene oxide onto H-functional starter substances and have a proportion of ethylene oxide in the polyether chain of greater than 20% by weight, preferably greater than 25% by weight, particularly preferably greater than 35% by weight and in particular greater than 50% by weight, based on the weight of the alkylene oxides used, which comprises the steps a) neutralization of the polyether alcohol with an acid subsequent to the addition reaction of the alkylene oxides, b) addition of at least one absorbent, c) removal of water and volatile compounds from the polyether alcohol, d) removal of the salts formed and the absorbents from the polyether alcohol, wherein phosphoric acid is used as acid in step a) in an amount of from 56 to 98% of the stoichiometric amount, the absorbent is used in an amount of from 0.
