Abstract
Procedimiento continuo para la fabricación de diaminas y/o poliaminas aromáticas mediante la hidrogenación catalítica de los dinitrocompuestos y/o polinitrocompuestos aromáticos correspondientes con hidrógeno, caracterizado porque en un reactor con lecho catalítico fijo o con lecho de rociado, a una presión en el intervalo entre 5 y 100 bar y a una temperatura de reacción en el intervalo de 100 hasta 220 C, a) se incorporan en una corriente de producto, compuesta sustancialmente por el producto de hidrogenación retornado, por agua y por hidrógeno, los dinitrocompuestos y/o polinitrocompuestos aromáticos y b) el calor de la reacción se evacua mediante un intercambiador de calor exterior y c) una parte de la corriente del producto se retira de forma continua del sistema de reactor.
