A process for obtaining pentafluoroethane HFC 125 byndismutation of gaseous tetrafluorochloroethane HCFC 124, atntemperatures in the range 200°-300°C, on a trivalent chromiumnoxide (Cr 2 O 3 ) catalyst, supported on aluminum fluoride, bynfeeding HF in such amount that the HCFC 124/HF molar ratio isnin the range 10/1-1/1. |
