| titleOfInvention | Process for producing pentafluoroethane |
| abstract | Object There is provided a process of effectively separating pentafluoroethane (HFC-125) out of a mixture of HFC and chloropentafluoroethane (CFC-115). Constitution When the mixture of HFC-125 and CFC-115 is subjected to extractive distillation so as to obtain concentrated HFC-125, methanol, ethanol, butanol, propyl alcohol, pentafluoropropanol, tetrafluoropropanol or acetone is used as an extractant, whereby CFC-115 is obtained as a distillate product and a mixture of HFC-125 and the extractant as a bottom product is obtained. Then, the extractant is separated from HFC-125 by distilling the mixture and re-used in the extractive distillation. <IMAGE> |
