Abstract

La presente invención se refiere a un proceso de purificación de soluciones de sal de leucoíndigo, para la eliminación de aminas aromáticas, particularmente anilina y N-metilanilina, comprendiendo: añadir a un vaso de purificación una solución de sal de leucoíndigo que tiene aminas aromáticas, dicha solución en la forma de una masa estacionaria; burbujear con flujo controlado un gas inerte en el vaso de purificación, por medio de dispositivo sumergido en la superficie de la masa estacionaria; inyectar con flujo controlado una corriente de gas de purificación en el vaso, por medio de un dispositivo sumergido en la masa estacionaria; y recuperar la solución purificada del vaso. Además, se refiere al uso de un gas inerte en el proceso de purificación de soluciones de sal de leucoíndigo, actuando como gas antiespumante, con el fin de reducir espuma y posibilidad de arrastre del producto en el procesamiento.
