Abstract

PROCEDIMIENTO PARA LA OBTENCION DE DISOLUCIONES CONCENTRADAS DE COLORANTES COMPLEJOS, CONSTITUIDOS POR UN 20-40 POR 100 DE COLORANTES COMPLEJOS DE METAL, LIBRES DE GRUPOS SULFO, EN MONOALQUILETERES DE ALCOHOLES Y AGUA. SE COPULA EL COLORANTE EN PRESENCIA DE UN MONOALQUILETER DE UN ALCOHOL Y AGUA, Y A CONTINUACION SE METALIZA CON UN COMPUESTO DE COBALTO O CROMO. SE AÑADEN SALES INORGANICAS, TALES COMO NACL Y NA2SO4, Y SE EFECTUA LA SEPARACION DE FASES A UNA TEMPERATURA ENTRE 60 Y 100 GC, AISLANDO LA FASE ORGANICA QUE CONTIENE EL COLORANTE.
