A process for preparing 2,3,3,3-tetrafluoropropene (CF3CF═CH2). 3,3,3-trifluoro-2-chloropropene (CF3CCl═CH2) is fluorinated with HF in the vapour phase in the presence of a chromia-containing catalyst to produce an intermediate composition 1,1,1,2,2-pentafluoropropane (CF3CF2CH3), which is dehydrofluorinated to produce CF3CF═CH2.
