Abstract

LAS MEMBRANAS DE OSMOSIS INVERSA PERMEABLES AL AGUA SE PREPARAN POLIMERIZANDO INTERFACIALMENTE SOBRE UN SOPORTE MICROPOROSO UN REACTANTE DE POLIAMINA ESENCIALMENTE MONOMERICA QUE TENGA AL MENOS DOS GRUPOS AMINOS FUNCIONALES POR MOLECULA DE REACTANTE, Y UN ALURO DE ACIL CICLOALIFATICO DE ANILLO SIMPLE POLIFUNCIONAL, ESENCIALMENTE MONOMERICO QUE TENGA MENOS DE 6 ATOMOS DE CARBONO POR ANILLO Y QUE TENGA UNA MEDIA DE ALREDEDOR 2.2 GRUPOS DE ALURO DE ACIL POR MOLECULA DE REACTANTE. LA POLIMERIZACION SE LLEVA PREFERIBLEMENTE A CABO EN LA PRESENCIA DE UNA SAL DE AMINO MONOMERICO, QUE INCREMENTA LA RELACION DE FLUJO DE LA MEMBRANA RESULTANTE. ADEMAS, PUEDE USARSE UN ALURO DE ACIL AROMATICO POLIFUNCIONAL EN CONJUNCION CON EL ALURO DE ACIL CICLOALIFATICO PARA INCREMENTAR LAS PROPORCIONES DE RECHAZO A LA SAL. LOS ALUROS DE ACIL CICLOALIFATICO MAS ADECUADOS SON CLORURO DE ACIDO TETRACARBOXILICO DE 1-CIS, 2-TRANS, 3-CIS, 4-TRANS CICLOPENTANO, CLORURO DE ACIDO TRETRACARBOXILICO 1-CIS, 2-TRANS, 3-CIS, 4-TRANS CICLOBUTANO Y CLORURO DE ACIDO TRICARBOXILICO DE 1-CIS, 2-TRANS, 4-CIS CICLOPENTANO. LA PREPARACION DE LOS NUEVOS ISOMEROS ALTERNATIVOS CIS / TRANS DE LOS ALUROS DEL ACIDO POLICARBOXILICO CICLOALIFATICO SE LLEVA A CABO USANDO SALES DE METAL DE LOS ACIDOS POLICARBOXILICOS DE TODOS LOS CIS.
