Abstract
The invention relates to the purification of pentafluoroethane (F125) containing chloropentafluoroethane (F15). The F-125-F115 mixture to be purified is subjected to a fluorination stage to convert F115 into hexafluoroethane (F116) which is then separated from F125, for example by distillation.
