PROCESSES FOR PURIFICATION AND PRODUCTION OF FLUOROCARBONS |
| 摘要 |
The present invention involves processes that utilize an olefinic compound, in particular, hexafluoropropene HFP or chlorotrifluoroethene CFC-1113 as extracting agents in the purification of pentafluoroethane HFC-125. These processes can utilize recovered HFP as a precursor for the production of heptafluoropropane HFC-227 or other derivatives.
