Abstract
Process for obtaining halogenated hydrocarbons and mixtures thereof, especially 2-bromo-2-chloro-1: 1: 1- trifluoroethane, O-bromo-1: 2-dichloro-1: 1-difluoroethane, or a mixture of these compounds, characterized by comprising heating 1: 2-dibromo-1: 1: 2-trichloroethane with practically anhydrous hydrogen fluoride, at a temperature of the order of 90º to 200ºC and in the presence of an antimony fluorochloride catalyst which containing at least 20% pentavalent antimony and separating from the reaction product said 2-bromo-2-chloro-1: 1: -difluoroethane, or 2-bromo-1: 2-dichloro-1: 1-difluoroethane, or a mixture of these compounds as desired.
