Method for purifying pentafluoroethane |
| abstract |
(57) [Summary] (Modified) [Structure] In purifying the pentafluoroethane from an unpurified mixture containing at least chloropentafluoroethane and pentafluoroethane, (A) the unpurified mixture and hydrogen Is subjected to a gas phase reaction in the presence of a catalyst to reduce the chloropentafluoroethane, and (B) the reaction mixture thus produced is formed from a first mixture mainly composed of hydrogen and mainly pentafluoroethane. And step (C) after removing hydrogen chloride from the first mixture until the amount becomes 0.5 times or less with respect to chloropentafluoroethane in the unpurified mixture. , This first And a step C of adding the mixture of 1. to the unpurified mixture. [Effect] Chloropentafluoroethane can be efficiently removed at low cost without lowering reactivity (or activity), and pentafluoroethane can be obtained in high yield. |
