Abstract
Se propone un procedimiento para preparar, por medio de la síntesis de Strecker, soluciones acuosas de sales trialcalinometálicas de ácido metilglicin-N,N-diacético con alto rendimiento y alto grado de pureza, partiendo de una solución acuosa de a-alanina, por transformación con formaldehído y ácido cianhídrico en solución acuosa para dar a-alanina-N,N-diacetonitri lo en una unidad de reacción, y saponificación de éste con una base para dar la correspondiente sal trialcalinometálica de ácido metilglicin-N,N-diacético, caracterizado porque la a-alanina se neutraliza parcialmente y porque el añadido de formaldehído y ácido cianhídrico para obtener el a-alanina-N,N-diacetonitrilo se maneja de tal manera que la concentración de ácido cianhídrico libre en la mezcla de reacción líquida quede en todo momento hasta tal punto limitada que reacciones secundarias, en particular las que dan formaldehidocianhidrina, incluso reacciones que resultan de la formaldehidocianhidrina, así como la polimerización de ácido cianhídrico sólo se produzcan en la medida necesaria para que se observen las exigencias de especificación en cuanto a la sal trialcalinometálica de ácido metilglicin-N,N-diacético, en particular las referentes al contenido del ácido nitrilotriacético y al color.
