Abstract
ES DESCUBIERTO UN METODO PARA RECUPERAR TRIMETILBENCENOS DE ALTA PUREZA EN EL QUE TALES COMPONENTES ESTAN CONTENIDOS JUNTO CON ETIL-TOLUENO Y POSIBLEMENTE TAMBIEN BUTIL-BENCENOS; CUYO METODO CONSTA DE TRATAR TALES MEZCLAS CON BENCENO EN LA PRESENCIA DE UN CATALIZADOR ACIDICO HETEROGENEO SELECCIONADO DEL GRUPO QUE CONSTA DE LAS TIERRAS ACIDICAS SODICHAS Y ALGUNOS TIPOS DE CATALIZADORES CRISTALINOS, POROSOS EN SU FORMA PROTONICA, BAJO CONDICIONES DE TRANSALQUILACION, Y DE SUBSECUENTEMENTE SEPARAR LOS TRIMETILBENCENOS POR DESTILACION. DE HECHO, LA TRANSALQUILACION CON BENCENO LA HACE POSIBLE EL ETIL-TOLUENO, Y EN PARTICULAR EL ETIL-TOLUENO-2 PARA SER PREFERENCIALMENTE O SELECTIVAMENTE CONVERTIDO EN TOLUENO Y ETILBENCENO, Y ALGUNO POSIBLEMENTE PRESENTA BUTI-BENCENOS PARA SER DRASTICAMENTE REDUCIDOS EN CANTIDAD, PERMITIENDO ASI UNA FACIL SEPARACION DE LOS TRIMETILBENCENOS, Y EN PARTICULAR DE PSEUDOCUMENO Y MESITILEN A SER ACOPLADOS POR MEDIO DE UN SIMPLE PASO DE DESTILACION.
