Abstract

UN PROCESO CONTINUO PARA LA DINITRACION DE DERIVADOS ALQUILSUSTITUIDOS DE FENOL Y ANILINA, UTILIZANDO ACIDO NITRICO SUSTANCIALMENTE LIBRE DE ACIDO SULFURICO, CARACTERIZADO PORQUE LA DINITRACION SE LLEVA A CABO EN UN UNICO PASO EN UN REACTOR TUBULAR EN PRESENCIA DE UNA CANTIDAD CATALITICAMENTE EFECTIVA DE UN CATALIZADOR CAPAZ DE REACCIONAR CON EL ACIDO NITRICO PARA FORMAR ACIDO NITROSO IN SITU.
