Abstract
Procedimiento para preparar anilinas sustituidas en posición meta por cloro, por hidrogenación catalítica en fase líquida, en medio ácido, en caliente y a presión, de derivados bencénicos nitrogenados y clorados, en presencia de metales nobles del grupo VII de la clasificación periódica, caracterizado porque los derivados bencénicos tienen la fórmula **fórmula** en la que Y representa el átomo de hidrógeno o átomo de oxígeno , X ` y X''`, idénticos o diferentes entre ellos, representan cada uno un átomo de cloro o un radical alcohilo o arilo o aralcohilo o alcoxilo o aralcoxilo eventualmente sustituido, pudiendo uno de los X'' y X''` ser además hidrógeno, R, R''` y R''`'', idénticos o diferentes entre si, representan cada uno un átomo de cloro o un radical alcohilo o aralcohilo o alcoxilo o ariloxilo eventualmente sustituido, representando al menos uno de esos tres símbolos el átomo de cloro, pudiendo como máximo dos de los R'', R''` o R''`'' ser además hidrógeno, y porque la reacción se efectúa en presencia de cationes metálicos pesados que pertenecen a una de las columnas 1b a 5a de la clasificación periódica.
