Abstract

La presente invención esta relacionada con un proceso para la fluorización en fase de vapor en la presencia de un compuesto metálico de transición-catalizador de compuesto de cromo de un halógeno conteniendo no mas de tres átomos de carbono y al menos un halógeno aparte del flúor, de tal forma que al menos uno de los halógenos aparte del flúor esté reemplazado por el flúor. el catalizador comprende un compuesto de cromo y al menos un compuesto metálico de transición seleccionado del grupo que consiste en óxidos,fluoruros,oxifluoruros y sales ácidas de Ni,Pd y Pt.The present invention is related to a process for vapor phase fluoridation in the presence of a chromium compound transition metal-catalyst compound of a halogen containing not more than three carbon atoms and at least one halogen apart from fluorine, such that at least one of the halogens apart from the fluorine is replaced by the fluorine. the catalyst comprises a chromium compound and at least one transition metal compound selected from the group consisting of oxides, fluorides, oxyfluorides and acidic salts of Ni, Pd and Pt.
