Abstract

La invencion se refiere a una solucion acuosa de una sal de sodio xNa+yH+ del compuesto quelante de la formula (I) (ver formula (I)): en donde x=2.1-2.7, y=0.9-0.3, y x+y=3; la invencion tambien se refiere a un contenedor que comprende por lo menos 0.5 kg de dicha solucion acuosa y a un metodo para preparar una solucion acuosa que comprende por lo menos 45% en peso de la sal de sodio xNa+yH+ del compuesto quelante de la formula (I), a partir de Na3-HEDTA, que comprende los pasos de someter a electrodialisis una solucion acuosa que contiene menos del 42% en peso de Na3-HEDTA usando una membrana bipolar, convirtiendo de esta manera la solucion de sal de trisodio en la solucion de la sal de sodio de la formula (I) con x=2.1-2.7 y=0.9-0.3, y x+y=3.
