PURIFICATION OF PENTAFLUOROETHANE
A method for recovering essentially pure pentafluoroethane [HFC 125] from mixtures thereof with chloropentafluoroethane [CFC 115] comprising extractive distillation using an extractive agent selected from bromochloro-2,2,2-trifluoroethane and perfluorocarbons of 5 or more carbon atoms such as perflu...

| description | A method for recovering essentially pure pentafluoroethane [HFC 125] from mixtures thereof with chloropentafluoroethane [CFC 115] comprising extractive distillation using an extractive agent selected from bromochloro-2,2,2-trifluoroethane and perfluorocarbons of 5 or more carbon atoms such as perfluoroalkanes and liquid perfluoropolyethers.
Un procédé, qui permet d'obtenir du pentafluoroéthane (HCF 125) très pur à partir de ses mélanges avec du chloropentafluoroéthane (CFC 115), consiste en une distillation extractive à l'aide d'un agent d'extraction choisi parmi le bromochloro-2,2,2-trifluoroéthane et des perfluorocarbones à 5 atomes de carbone ou plus, tels que les perfluoroalcanes et les perfluoropolyéthers liquides. |
