    摘要: What is proposed is a process for preparing aminopolycarboxylates proceeding from the corresponding polyalkanolamines by oxidative dehydrogenation in the presence of a catalyst comprising 1 to 90% by weight of copper, based on the total weight of the catalyst, using a base, which comprises first performing a partial conversion of the polyalkanolamine to a reaction mixture comprising the aminopolycarboxylate at a temperature in the range from 140 to 180° C. until at least 10 to 90 mol % of the polyalkanolamine has been depleted, and then continuing the conversion at elevated temperature.

    摘要: The present invention relates to a process for preparing aminopolycarboxylates proceeding from an amino acid which, in a first process step is reacted with ethylene oxide to give an intermediate mixture comprising the corresponding dialkanolamine, and then the intermediate mixture, in a second process step is converted catalytically using a base to the corresponding aminopolycarboxylate, wherein the amino acid, before the reaction with ethylene oxide in the first process step, is supplied to a partial neutralization with 0.70 to 0.99 equivalent of base per acid group, or, in the first process step, an amino acid which has already been partly neutralized with 0.70 to 0.99 equivalent of base per acid group is used.
