<p>Process for the removal of chlorine-containing impurities, for example chloropentafluoroethane, and/or hydrofluoroalkane impurities, for example 1,1,1,2-tetrafluoroethane, from pentafluoroethane which comprises contacting the impure pentafluoroethane with hydrogen at elevated temperature, for example 350-600 °C, in the presence of a hydrogenation catalyst, for example palladium-on-carbon, to convert the impurity or impurities to a hydrofluoroalkane and/or a hydrocarbon.</p> |
