Abstract
PROCEDIMIENTO PARA AISLAR COMPUESTOS ACIDOS, SOLUBLES EN AGUA, MEDIANTE ADSORCION EN RESINAS ADSORBENTES BASICAS. CONSISTE EN PONER EN CONTACTO LAS SOLUCIONES ACUOSAS ACIDAS CON RESINAS ADSORBENTES DEBILMENTE BASICAS. LOS COMPUESTOS ACIDOS ADSORBIDOS SE DESORBEN CON AGUA A UNA TEMPERATURA DE 1 HASTA 100 GRADOS. LAS RESINAS CARGADAS CON LAS SOLUCIONES SE LAVAN, ANTES DE LA DESORCION, CON AGUA O CON DISOLVENTES ORGANICOS. LA RESINA ADSORBENTE DEBILMENTE BASICA ES UN INTERCAMBIADOR DE ANIONES DEBILMENTE BASICO FORMADO POR POLIMEROS A BASE DE UN 10 A UN 20% DE VINILIMIDAZOL, DE UN 0 A UN 80% DE N-VINIL-N-METILACETAMIDA Y DE UN 0,1 A UN 50% DE METILENBISACRILAMIDA.
