Abstract
La presente invención se refiere a un procedimiento para la preparación de 1,1,1-trifluorodicloroetano y 1,1,1,2-tetrafluorocloroetano por fluoración de un tetrahaloetileno, C2C14-xFx en donde x es igual a 0 a 3, caracterizado porque comprende contactar en la fase gaseosa de aproximadamente 300 grados C a aproximadamente 450 grados C el tetrahaloetileno HF con un catalizador, que comprende cuando menos un metal en un estado de oxidación mayor a cero, el metal se elige del grupo que consiste de cromo, manganeso, níquel y cobalto, en un soporte que comprende esencialmente aluminio, oxígeno y flúor en proporciones tales que el contenido de flúor corresponde a un contenido de A1F3 de cuando menos 90 por ciento en peso de la composición catalizadora, excluyendo el metal, el contenido de A1F3 se obtiene por pretratamiento con HF.
