Abstract

"ARENAS" DE VANADIO DONDE "ARENA" SIGNIFICA BENZENO O MONO-, DI-, POLI ESTOS SE PREPARAN POR MEDIO DE UN PROCESO QUE COMPRENDE: (A) FORMAR UN COMPLEJO POR MEDIO DE UNA REACCION ENTRE EL TRICLORURO DE VANADIO, METAL DE ALUMINIO Y TRICLORURO DE ALUMINIO, REALIZANDOLA EN PRESENCIA DE LA "ARENA" ELEGIDA. (B) TRATAR EL COMPLEJO ANTERIORMENTE OBTENIDO CON UN ETER LIQUIDO CICLICO, ACICLICO, O ALIFATICO, PARA OBTENER LA REDUCCION DE "FORMULA" A "FORMULA". (C) RECUPERAR LA "ARENA" DE VANADIO ASI OBTENIDA. LAS "ARENAS" DE VANADIO SON UTILES EN LA PREPARACION DE CATALIZADORES PARA LA POLIMERIZACION DE LA OLEFINA.
