Abstract

ES UN PROCESO PARA LA SEPARACION SELECTIVA POR ADSORCION DEL 3,5-DIETILTOLUENO (3,5-DET) O 2,6-DIETILTOLUENO (2,6-DET) DE UNA MEZCLA QUE CONSTA DE AL MENOS UN ISOMERO DEL GRUPO 3,5-DET O 2,6-DET Y AL MENOS UN ISOMERO DET, MEDIANTE LA PUESTA EN CONTACTO DE LA MEZCLA DE ALIMENTACION, EN CONDICIONES DE ADSORCION, CON UN ADSORBENTE SELECCIONADO DE LOS GRUPOS QUE CONSTAN DE A) UNA X ZEOLITA INTERCAMBIADA CON UN CATION DE POTASIO; B) UNA X ZEOLITA INTERCAMBIADA CON SODIO, COBRE O UNA Y ZEOLITA INTERCAMBIADA CON COBRE, SODIO, BARIO O CALCIO; C) UNA X ZEOLITA INTERCAMBIADA CON BARIO O LITIO O CON POTASIO O BARIO O UNA Y ZEOLITA INTERCAMBIADA CON POTASIO, SODIO, BARIO O CALCIO, POR LO QUE SELECTIVAMENTE SE ADSORBEN UNO DE LOS ISOMEROS DET CONTENIDOS EN LA MEZCLA; POR LO QUE SELECTIVAMENTE SE ADSORBEN UNO O MAS DE DICHOS ISOMEROS DET Y SE EXTRAE SELECTIVAMENTE UNO O MAS ISOMERO(S) RELATIVAMENTE NO-ADSORBIBLES EN CONTACTO CON EL ADSORBENTE PARA FORMAR UN REFINADO, SIN VAPOR, EN EL ISOMERO ADSORBIDO RELATIVO A LA MEZCLA DE ALIMENTACION Y POSTERIORMENTE CONTACTANDO EL ADSORBENTE ENRIQUECIDO CON UN DE-ABSORBENTE QUE COMPRENDE UN HIDROCARBURO AROMATICO ALQUILO-SUSTITUIDO MONOCICLICO EN CONDICIONES DE ADSORCION EFECTIVAS PARA FORMAR UN EXTRACTO DE VAPOR ENRIQUECIDO, CON RESPECTO A LA MEZCLA DE ALIMENTACION, EN EL ISOMERO ADSORBIDO.
