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 se utiliza ácido nítrico sustancialmentle libre de ácido sulfurico, que se caracteriza porque la dinitracion se lleva a cabo en una sola etapa en un reactor tubular en presencia de una cantidad catalíticamente efectiva de un catalizador capaz de reaccionar con el ácido nítrico para formar ácido nitroso in situ.
