Abstract
La presente se refiere a un proceso de purificación de soluciones de sal de leucoíndigo, para la eliminación de aminas aromáticas, particularmente anilina y N-metilanilina, que comprende las etapas de: adicionar a un vaso de purificación una solución de sal de leucoíndigo conteniendo aminas aromáticas, en que dicha solución está en la forma de una masa estacionaria; burbujear con flujo controlado un gas inerte en el vaso de purificación, por medio de un dispositivo sumergido en la superficie de la masa estacionaria; inyectar con flujo controlado una corriente gaseosa de purificación en el vaso, por medio de un dispositivo sumergido en la masa estacionaria; y recuperar la solución de sal de leucoíndigo purificada del vaso. Además, la presente se refiere al uso de un gas inerte en un proceso de purificación de soluciones de sal de leucoíndigo, actuando como un antiespumante gaseoso, capaz de reducir la ocurrencia de espuma y la consecuente posibilidad de arrastre del producto de interés durante el procesamiento de purificación del mismo.
