Abstract
Un procedimiento de preparación de anilinas sustituidas en posición meta por cloro, por hidrogenación catalítica en fase líquida, en medio ácido, en caliente y bajo presión, de derivados bencénicos nitrogenados y clorados, en presencia de metales nobles del grupo VIII de la clasificación periódica, caracterizado por el hecho de que los derivados bencénicos tienen la fórmula **fórmula** en la cual Y representa el átomo de hidrógeno o el átomo de oxígeno, X'' y X''`, idénticos o diferentes entre si, representan cada uno un átomo de cloro o un radical alcohilo o arilo o aralcohilo o alcoxilo o aralcoxilo eventualmente sustituido,pudiendo ser uno de X'' y X''` además hidrógeno , R'' , R''` y R''`'', idénticos o diferentes entre sí, representan cada uno un átomo de cloro o un radical alcohilo o aralcohilo o alcoxilo o ariloxilo eventualmente sustituido, representando al menos uno de estos tres símbolos el átomo de cloro, pudiendo ser a lo sumo dos de R'', R''` o R''`'', además hidrógeno, y porque la reacción se efectúa en presencia de iones cloruros en cantidad tal que la relación de las concentraciones [Cl-]/[H+] sea superior a 1,5
