Abstract
Un proceso continuo para la dinitracion de los derivados del fenol y de la anilina a los que se les ha sustituido H por grupos alquilos y en el que seutiliza ácido nítrico sustancialmente libre de ácido sulfurico que se caracteriza porquela dinitracion se lleva a cabo en una sola etapa en unreactor tubular en presencia de una cantidad catalíticamente efectiva de un catalizador capaz de reaccionar con el ácido nítrico para formar ácido nitrosoin situ.
