Process for the purification of saturated hydrofluorocarbons |
摘要 |
In order to remove olefinic impurities present in a hydrofluorocarbon such as pentafluoroethane (R-125), the impure hydrofluorocarbon is treated with oxygen in the absence of catalyst or of active charcoal. The process is well suited to the purification of fluoroethanes and, more particularly, to that of pentafluoroethane.
