Abstract

Un reactor para la nitración de hidrocarburos en fase gaseosa, bajo presión, constituido por un recinto de reacción, en el interior del cual un haz tubular está en contacto con un fluido portador de calor de fuerte capacidad de intercambio térmico, caracterizado porque el fluido portador de calor se elige de tal modo que la temperatura de la superficie exterior de los tubos se mantenga constante a alrededor de 20ºC entre el punto más caliente y el punto más frío, estando comprendida la relación de la superficie del haz tubular en contacto con el medio de reacción al volumen del recinto de reacción entre 0,1 y 20, y siendo el perímetro interior de los tubos del haz como máximo igual a 800 mm.
