Abstract
Se describe un procedimiento para la fabricacion de pentafluoroetano [HFC 125] mediante la reaccion de percloroetileno con fluoruro de hidrogeno en la fase de vapor sobre un catalizador fluoracion, en un reactor de fluoracion, con la recirculacion de diclorotrifluoroetano [HCFC 123] y clorotetrafluoroetano [HCFC 124] hacia el reactor de fluoracion, en donde el tetrafluoroetano [HFC 134a] es también recirculado hacia el reactor de fluoracion. El tetrafluoroetano y el clorotetrafluoroetano ambos pueden ser separados de la corriente de producto en una columna de destilacion individual y recirculados conjuntamente hacia el reactor de fluoracion.
