Abstract

Un procedimiento para la fabricacion de ácido N-fosfonometiliminodiacético (PMIDA) que comprende las etapas de: (a) neutralizacion de una solucion acuosade la sal de sodio o potasio del ácido iminodiacético (Na2IDA o K2IDA) con un ácido mineral fuerte a temperaturas de 10 a 80*C; (b) separacion del ácidoiminodiacético (IDA) de la solucion de reaccion de la etapa (a); (c) transformacion del ácido iminodiacético con formaldehído y ácido fosforoso en solucionacuosa, en presencia de un ácido mineralfuerte a temperaturas de 100 a 150*C, en caso dado bajo atmosfera de un gas de proteccion, para formar el ácidoN-fosfonometiliminodiacético; y (d) separacion del ácido N-fosfonometiliminodiacético de la solucion de reaccion de la etapa (c), por ejemplo por filtracion;método en el cual la solucion de reaccion acuosa de la etapa (d) (aguas madres), que contiene pequenas cantidades de ácido N-fosfonometiliminodiacético,componentes de reaccion y productos secundarios, es reciclada a la etapa de neutralizacion (a). De este modo es posible lograr no solamente una disminucion delnumero de corrientes de desechos, sino también una reduccion cuantitativa drástica de la cantidad total de la corriente de desechos, pudiéndose renunciar a laseparacion por esclusado de una cantidad parcial, usual con otros métodos de reciclado.A process for the manufacture of N-phosphonomethyliminodiacetic acid (PMIDA) comprising the steps of: (a) neutralization of an aqueous solution of the sodium or potassium salt of the iminodiacetic acid (Na2IDA or K2IDA) with a strong mineral acid at temperatures of 10 at 80 * C; (b) separation of the iminodiacetic acid (IDA) from the reaction solution of step (a); (c) transformation of the iminodiacetic acid with formaldehyde and phosphorous acid into a solution, in the presence of a strong mineral acid at temperatures of 100 to 150 * C, if necessary under the atmosphere of a protective gas, to form the N-phosphonomethyliminodiacetic acid; and (d) separation of the N-phosphonomethyliminodiacetic acid from the reaction solution of step (c), for example by filtration; method in which the aqueous reaction solution of step (d) (mother liquor), which contains small amounts of N-phosphonomethyliminodiacetic acid, reaction components and secondary products, is recycled to the neutralization stage (a). In this way it is possible to achieve not only a decrease in the number of waste streams, but also a drastic quantitative reduction of the total amount of the waste stream, being able to give up the separation by blocking a partial amount, usual with other recycling methods.
