Abstract
Se describe un proceso continuo para la preparación de mezclas isoméricasde dinitrotolueno, mediante una nitración del tolueno, en una sola etapa,bajo condiciones adiabáticas. La entalpía de la reacción se usa para laremoción, mediante la destilación, del agua de reacción formada durante lanitración. En este proceso, el tolueno se hace reaccionar con un ácidonitrante que tiene desde aproximadamente 80 a aproximadamente 100% en pesode un componente inorgánico que tiene una composición específica y desdeaproximadamente 0 a aproximadamente 20% en peso de un componente orgánicoque tiene una composición específica.
