Abstract
La presente invención se refiere a un procedimiento para la purificación de diaminomaleonitrilo, a partir de una mezcla cruda producida por la tetramerización del cianuro de hidrógeno y conteniendo: diaminomaleonitrilo; un polímero más alto de cianuro de hidrógeno que el diaminomaleonitrilo tetramérico el cual es soluble, en un solvente para diaminomaleonitrilo; y un polímero más alto de cianuro de hidrógeno que el diaminomaleonitrilo tetramérico el cual es insoluble en un solvente para el diaminomaleonitrilo, caracterizado porque comprende calentar la mezcla cruda en aire, nitrógeno o un líquido orgánico que tenga un punto de ebullición de 90°C o superior y una solubilidad para el diaminomaleonitrilo de 0.1 o menos a una temperatura de aproximadamente 90 a 140°C por aproximadamente 0.5 a 5 horas por medio de la cual el polímero de cianuro de hidrógeno más elevado que es soluble en un solvente de diaminomaleonitrilo se convierte a polímero de cianuro de hidrógeno más elevado adicional el cual es insoluble en un solvente de diaminomaleonitrilo; separar el diaminomaleonitrilo del polímero más alto insoluble por extracción con un solvente de diaminomaleonitrilo, y remover el solvente de la solución de diaminomaleonitrilo resultante para obtener diaminomaleonitrilo de una pureza de apoximadamente 99 por ciento.
