摘要: The present invention relates to a process for preparing aminocarboxylates, proceeding from amines, by employing a reaction sequence composed of ethoxylation to amino alcohols and subsequent oxidative dehydrogenation to the corresponding aminocarboxylates, especially the alkali metal or alkaline earth metal salts of the complexing agents MGDA (methylglycinediacetic acid), EDTA (ethylenediaminetetra-acetic acid) and GLDA (glutamic acid diacetic acid) or the free acids thereof.
