Abstract

UNA COMPOSICION DE CARGA QUE CONTENGA (I) UN ALCOHOL QUE TENGA MENOS DE TRES ATOMOS DE CARBONO Y (II) UN OXIGENADO SELECCIONADO DE ETERES ORGANICOS, ALDEHIDOS, QUETONES, Y ESTERES SE PASA EN CONTACTO CON UN PRIMER LADO DE UNA CAPA DE SEPARAION DE MEMBRANA NO POROSA QUE CONSTA DE UNA MEZCLA DE ALCOHOL DE POLIVINILO Y UN ACIDO POLIACRILICO SOBRE UNA CAPA DE SOPORTE DE POLIACRILONITILO; CON UNA CAIDA DE PRESION A LO LARGO DE LA CAPA SEPARADORA NO POROSA DESDE EL PRIMER LADO (PRESION ALTA) HASTA EL SEGUNDO LADO (PRESION BAJA). AL MENOS UNA PORCION DE ALCOHOL DE LA COMPOSICION DE CARGA Y UNA PORCION MENOR DE OXIGENADO PASA MEDIANTE PERVAPORACION A TRAVES DE LA CAPA DE SEPARACION NO POROSA COMO UNA MEZCLA POBRE QUE CONTIENE MAS ALCOHOL Y MENOS OXIGENADO QUE LOS PRESENTES EN DICHA COMPOSICION DE CARGA, DEJANDO UN LIQUIDO RICO QUE CONTIENE MENOS ALCOHOL Y MAS OXIGENADO QUE LOS PRESENTES EN DICHA COMPOSICION DE CARGA; LA MEZCLA POBRE, EN FASE DE VAPOR A UNA PRESION EN QUE SU PRESION DE VAPOR SE RECUPERA CUANDO PENETRA DESDE EL LADO DE PRESION BAJA DE LA CAPA DE SEPARACION NO POROSA
