The subject of the invention is a process for the preparation of 2,3,3,3-tetrafluoro-1-propene which comprises the following stages: (i) dehydrofluorination of 1,1,1,2,2,3-hexafluoropropane to 1,2,3,3,3-pentafluoro-1-propene; (ii) hydrogenation of the 1,2,3,3,3-pentafluoro-1-propene obtained in the preceding stage to 1,1,1,2,3-pentafluoropropane; and (iii) dehydrofluorination of the 1,1,1,2,3-pentafluoropropane obtained in the preceding stage to 2,3,3,3-tetrafluoro-1-propene. |
