METHOD FOR CLEANING PERFLUOR CARBON AND USE OF CLEANED PERFLUOR CARBON |
| abstract |
Described is a method for the purification of perfluorocarbons, or mixtures of perfluorocarbons, having impurities containing hydrogen and/or carbon-carbon double bonds. The impure perfluorocarbons or perfluorocarbon mixtures are reacted with strong aqueous bases in the presence of Ca<2+> or Ba<2+> ions and alcoholate ions together with secondary amines. |
