Abstract

Procedimiento para la obtención de soluciones acuosas concentradas de colorantes y blanqueadores, bajo separación de las sales inorgánicas y transformación de las sales sódicas, potásicas y alcalino-térreas del colorante en el caso de los colorantes aniónicos, o bien de los cloruros, sulfatos y metosulfatos en el caso de los colorantes catiónicos, en sales de más fácil solubilidad sin aislamiento intermedio de los ácidos o bien de las bases libres, caracterizado porque las sales inorgánicas se separan mediante un proceso de separación de membrana, y antes, durante o después de la separación de las sales inorgánicas originalmente existentes, en el caso de los colorantes y blanqueadores aniónicos se agregan 10-500 moles-%, referido al colorante, de sales de amonium.
