Abstract
Un procedimiento de preparación de anilinas sustituidas en posición meta con 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 arailo o aralcohilo o alcoxi o aralcoxi eventualmente sustituido, pudiendo uno de los sustituyentes X'' y X''` ser además , hidrógeno, R'' R''` y R''`'', idénticos o diferentes entre sí, representan cada uno un átomos de cloro o un radical alcohilo o aralcohilo o alcoxi o ariloxi eventualmente sustituido, representando al menos uno de estos tres símbolo el átomo de cloro, pudiendo como máximo dos de los sustituyentes R'', R''` y R''`'', ser ademas hidrógeno y por el hecho de que la reacción se efectúa en presencia de iones yoduro y/o bromuro
