Abstract

Un procedimiento combinado de separación de xileno y transalcohilación de tolueno, para producir benceno y ortoxileno que comprende las etapas de: a) transalcohilar una mezcla de tolueno y alcohilbenceno de C9 en una zona de transalcohilación en condiciones de transalcohilación para producir un efluente de la zona de transalcohilación que comprende benceno, tolueno, alcohilbencenos de C8, alcohilbencenos de C9 y alcohilbencenos de C10; b) fraccionar al menos una parte de dicho efluente de la zona de transalcohilación en una columna de destilación en la que se recuperan benceno y tolueno como fracción de cabeza y se recuperan benceno y tolueno como fracción de cabeza y se recuperan materiales más pesados que el tolueno como fracción de fondo.
