Perfluoropropene (PFP) hydrofluorination process in gaseous phase to obtain CF3-CHF-CF3 (A-227ea), characterized in that as catalyst fluorinated alumina containing at least 90% by weight of AlF3, is used, the HF/PFP molar ratios range from about 4:1 to 20:1, the hydrofluorination process temperature being in the range 320°-420° C.
