Abstract: Lo que se propone es un procedimiento para preparar aminopolicarboxilatos partiendo de las correspondientes polialcanolaminas por medio de deshidratación oxidativa en presencia de un catalizador que contiene de 1 a 90% en peso de cobre, tomando como referencia el peso total del catalizador, y aplicando una base, caracterizado porque, como primer paso, se efectúa una transformación parcial de la polialacanolamina para dar una mezcla de reacción que contiene el aminopolicarboxilato, a una temperatura que se halla dentro del intervalo de 140 a 180º C, hasta que se haya cumplido por lo menos un 10 a un 90% en moles de la reacción de la polialcanolamina, y luego se continúa llevando a efecto la transformación a una temperatura más elevada.

Abstract: The present invention relates to a method for the production of aminodicarboxylic acid-N,N,diacetic acids of the general Formula I, wherein X independently of one another represents hydrogen or an alkali metal and n represents a number 1 or 2. Furthermore, the invention relates to aminodicarboxylic acid-N,N-diacetic acids of high purity. The inventive method comprises the following steps: A.) reacting an aminodicarboxylic acid of the general Formula II, wherein X and n have the aforementioned meanings, with 0.8 to 1.2 mole equivalents of formaldehyde and with 0.8 to 1.2 mole equivalents of hydrocyanic acid; b) reacting the reaction products of step a) with 0.8 to 1.2 mole equivalents of hydrocyanic acid and with 0.8 to 1.2 mole equivalents of formaldehyde; c) hydrolyzing in the reaction product obtained in step b).
