Abstract

PROCEDIMIENTO PARA LA PREPARACION DE SOLUCIONES ACUOSAS ULTRACONCENTRADAS DE COLORANTES CATIONICOS. CONSISTE EN TRATAR A UNA TEMPERATURA COMPRENDIDA ENTRE 10 Y 95 GRADOS, UNA SOLUCION ACUOSA DILUIDA DEL COLORANTE CATIONICO EN FORMA DE SAL, CON UN ELECTROLITO CONSTITUIDO POR UNA SAL O UNA BASE INORGANICA, EN UNA PROPORCION TAL QUE SE FORME UN SISTEMA BIFASICO DE DOS FASES LIQUIDAS. POSTERIORMENTE SE SEPARA A DICHA TEMPERATURA LA SOLUCION ACUOSA ULTRACONCENTRADA DE COLORANTE QUE SE HA SEGREGADO DEL RESTO DE COMPONENTES. LA SOLUCION ACUOSA ULTRACONCENTRADA DE COLORANTE CONTIENE UN 30 A UN 90 POR 100 EN PESO, PREFERENTEMENTE DE UN 50 A UN 80 POR 100 EN PESO, PREFERENTEMENTE DE UN 45 A UN 15 POR 100 EN PESO, DE AGUA, Y UN 1 A UN 15 POR 100 EN PESO, PREFERENTEMENTE DE UN 2 A UN 8 POR 100 EN PESO, PREFERENTEMENTE DE UN 2 A UN 8 POR 100 EN PESO, DE LA SAL INORGANICA O DE LA BASE INORGANICA QUE INTEGRA EL ELECTROLITO QUE INTERVIENE EN EL TRATAMIENTO. DE USO EN LA PREPARACION DE COLORANTES SOLIDOS OLIQUIDOS ESTABLES EN ALMACENAMIENTO.
