Abstract

PARA PREPARAR 3,5 DIMETILFENOL POR DIMETILIZACION CATALITICA DE ISOFORON EN LA FASE GASEOSA, EN PRESENCIA DE UN METAL O UNA ALEACION DE METAL COMO CATALIZADOR, LA FASE MOVIL DEL PROCESO QUE CONTIENE ISOFORON ES CONDUCIDA POR ZONAS DE REACCION QUE CONTIENEN EL CATALIZADOR EN REACTIVIDAD ESCALONADA, Y LA FASE MOVIL DEL PROCESO SE TERMOSTATIZA ENTRE ESTAS ZONAS REACTIVAS, EN ZONAS QUE NO CONTIENEN NINGUN CATALIZADOR, CON LO CUAL EL CONTENIDO DE ISOFORON RESIDUAL DISMINUYE CLARAMENTE Y SE INCREMENTA LA PRODUCCION DE 3,5 DIMETILFENOL.
