Abstract

METODO DE FORMACION DE MEMBRANAS SEMIPERMEABLES. CONSISTE EN APLICAR SOBRE UN SUSTRATO UN POLIMERO QUE CONTIENE GRUPOS ARILO Y GRUPOS -SO3 OBTENIDO POR REACCION EN DOS FASES DE UN HALURO DE SULFONILO AROMATICO DIFUNCIONAL O UNA MEZCLA DE ESTOS COMPUESTOS EN UN DISOLVENTE ADECUADO, CON UN FENOL DIFUNCIONAL O UNA MEZCLA DE ESTOS FENOLES, EN MEDIO ACUOSO, CON FUERTE AGITACION EN PRESENCIA DE UN CATALIZADOR DE TRANSFERENCIA DE FASE; ELIMINACION DE DISOLVENTE POR EVAPORACION Y EXTRACCION DEL RESTO DE DISOLVENTE POR EXTRACCION. ESTAS MEMBRANAS TIENEN APLICACIONES EN OPERACIONES DE HIPERFILTRACI''ON.
