Abstract

LOS MONONITROTOLUOLES PUEDEN SER ELABORADOS MEDIANTE MEZCLA INTENSIVA UNO CON OTRO DE TOLUOL, ACIDO NITRICO, ACIDO SULFURICO Y AGUA AL MISMO TIEMPO O DE FORMA SUCESIVA EN SU CANTIDAD COMPLETA Y EN CASO DE ELABORACION CONTINUA REDISPERSADOS AL MENOS DOS VECES. SE UTILIZA UNA ENERGIA DE MEZCLA POR VOLUMEN DEL REACTOR DE 1 HASTA 40 W/L DE LA MEZCLA DE REACCION COMPLETA, CON PREFERENCIA 3 HASTA 30 W/L Y EN LA REALIZACION CONTINUA SE DEPRESIONA AMPLIAMENTE EL REMEZCLADO. SE CUMPLEN LAS CONDICIONES DE REACCION ADIABATICA.
