Abstract

METODO DE PREPARACION DE TORTAS PRENSADAS ACUOSAS, CONCENTRADAS DE COLORANTES AZOIDOS EN DISPERSION. CONSISTE EN AÑADIR, DURANTE LA PREPARACION DEL COLORANTE EN EDIO ACUOSO, COMO MUY TARDE ANTES DE SU AISLAMIENTO, UN TENSIOACTIVO NO IONOGENO O UNA MEZCLA DE TENSIOACTIVOS, QUE TIENEN EN DISOLUCION ACUOSA UN PUNTO DE ENTURBAMIENTO EN AGUA A UNA TEMPERATURA COMPRENDIDA ENTRE 5JC Y 90JC; SEGUIDO DEL AISLAMIENTO DEL COLORANTE AZOICO EN DISPERSION PASANDOLO A TRAVES DE UN FILTRO PRENSA, A UNA TEMPERATURA POR ENCIMA DEL PUNTO DE ENTURBIAMIENTO DEL TENSIOACTIVO O DE LA MEZCLA DE TENSIOACTIVOS EMPLEADOS. ESTAS TORTAS PRENSADAS TIENEN APLICACIONES PARA PRODUCIR PREPARACIONES DE COLORANTES EMPLEADAS EN TEÑIR MATERIALES NATURALES Y SINTETICOS.
