Abstract

Se obtiene la 2-trifluormetoxi-anilina, empleable como producto intermedio por ejemplo para la fabricacion de productos activos farmacéuticos y agroquímicos - con rendimientos muy buenos y con elevada pureza, por nitracion, en una primera etapa, del 1,2-dicloro-4-trifluormetoxi-benceno a temperaturas comprendidas entre -20 degree C y +80 degree C y por hidrogenacion catalítica, en una segunda etapa, de los productos de nitracion formados en la primera etapa (con inclusion de 1,2-dicloro-5-nitro-4-trifluormetoxi-benceno y 1,2-dicloro-3-nitro-4-trifluormetoxi-benceno), pudiéndose aislar, en caso dado, las anilinas formadas, de manera intermedia, correspondientes a los dos derivados del nitrobenceno, los citados derivados del nitrobenceno y las anilinas son compuestos nuevos y, como tales, constituyen también un objeto de la invencion.
