Abstract

LA INVENCION SE REFIERE A LA PRODUCCION DE ETILBENCENO A PARTIR DE ETILENO DILUIDO Y BENCENO DILUIDO, EN TRES ETAPAS. PRIMERAMENTE, LA CORRIENTE DE ALIMENTACION DE BENCENO SE ALQUILA CON LA CORRIENTE DE ALIMENTACION DE ETILENO DILUIDO, QUE CONTIENE ETILENO, PARA FORMAR ETILBENCENO JUNTO CON POLIETILBENCENOS (PEB), QUE INCLUYEN UNA MEZCLA DE DI- Y TRIETILBENCENO Y PUEDE CONTENER ASIMISMO TETRA-, PENTA- Y HEXAETILBENCENOS. EN SEGUNDO LUGAR, EL PRODUCTO DE LA PRIMERA FASE SE DESTILA PARA ELIMINAR EL BENCENO QUE NO HA REACCIONADO Y EL RESTO DE MATERIAL QUE NO HA REACCIONADO. PARTE DEL ETILBENCENO SE RECUPERA POR DESTILACION. EN UNA TERCERA FASE, SE TRANSALQUILAN LOS POLIETILBENCENOS CON BENCENO PURO EN EXCESO, PARA FORMAR EL PRODUCTO DE ETILBENCENO, QUE SE PUEDE RECUPERAR POR DESTILACION. DICHO PROCESO QUE EMPLEA UNA CORRIENTE DE ALIMENTACION DE BENCENO DILUIDO SE PUEDE APLICAR ASIMISMO A LA OBTENCION DE CUMENO, MEJOR QUE DE ETILBENCENO, UTILIZANDO UNA CORRIENTE DE ALIMENTACION DE PROPILENO DILUIDO. LOS CATALIZADORES UTILIZADOS PARA LAS FASES DE ALQUILACION Y TRANSALQUILACION SON CATALIZADORES DE HETEROPOLIACIDOS SOPORTADOS, COMO ACIDO FOSFOTUNGSTICO SOBRE UN SOPORTE DE SILICE O CATALIZADOR DE ZEOLITA Y EN FORMA ACIDA.
