Abstract: The present invention relates to a method for producing aminocarboxylates starting from amines using a reaction sequence of ethoxylation to form amino alcohols and subsequent oxidative dehydrogenation to form the corresponding aminocarboxylates, in particular the alkali or alkaline earth salts of the complexing agents MGDA (methylglycinediacetic acid), EDTA (ethylenediaminetetraacetic acid) and GLDA (glutamic acid diacetic acid) or the free acids thereof.

Abstract: The invention relates to a method for producing aminopolycarboxylates starting from the corresponding polyalkanol amines by means of oxidative dehydration in the presence of a catalyst containing 1 to 90 wt.% copper, with respect to the total weight of the catalyst, using a base. The method is characterized in that the polyalkanol amine is first partially reacted into a reaction mixture containing the aminopolycarboxylate at a temperature ranging from 140 to 180 °C until at least 10 to 90 mol% of the polyalkanol amine is reacted. The reaction is then continued at an increased temperature.
