Abstract

UN DIMETILNAFTALENO SE ISOMERIZA MEDIANTE CONTACTO EN FORMA LIQUIDA CON UN CATALIZADOR DE ISOMERIZACION SOLIDO QUE COMPRENDE BIEN UN ZEOLITO BETA O BIEN UN ZEOLITO CRISTALINO DE TIPO Y QUE TENGA UNA RELACION MOLAR SILICE/ALUMINIO DE ENTRE 4:1 Y 10:1 Y UNAS VENTANAS EN FORMA DE PORO SUMINISTRADAS POR ANILLOS DE 12 MIEMBROS QUE CONTIENEN OXIGENO Y UN TAMAÑO DE CELDA UNITARIA DE ENTRE 24.2 Y 24.7 ANGSTROM (10 ELEVADO A 10M). LA ISOMERIZACION SE REALIZA A UNA TEMPERATURA ELEVADA Y A UNA PRESION SUFICIENTEMENTE ALTA PARA MANTENER EL MATERIAL EN LA FASE LIQUIDA.
