Abstract

UN PROCEDIMIENTO PARA LA PREPARACION DE UN MATERIAL CAMBIADOR DE ION DE CELULOSA CARBOXILADA. CUSTA DE LAS SIGUIENTE ETAPAS: 1. CALENTAR UNA MEZCLA DE CELULOSA Y ACIDO CITRICO, ISOCITRICO O CONITICO QUE CONTIENE DE 30 A 70 POR 100 EN PESO DEL ACIDO, A UNA TEMPERATURA COMPRENDIDA ENTRE 100 Y 160 C, MIENTRAS SE SEPARA CONTINUAMENTE EL AGUA DE LA MISMA HASTA QUE LA CELULOSA HA REACCIONADO CON, POR LO MENOS, EL 20 POR 100 DE SU PROPIO PESO DE ACIDO. 2. TRATAR EL PRODUCTO CON UN ALCALI ACUOSO MANTENIDO A UN PH COMPRENDIDO ENTRE 8 Y 11 HASTA QUE LA CAPACIDAD CAMBIADORA DE ION DEL PRODUCTO RESPECTO A LOS IONES CUPRICOS ES, POR LO MENOS, DE 1,5 MILIEQUIVALENTES POR GRAMO.
