Abstract: The present invention relates to a process for the production of 2,3,3,3-tetrafluoropropene comprising the stages:
i) in a first reactor, bringing 2-chloro-3,3,3-trifluoropropene into contact with hydrofluoric acid in the gas phase in the presence of a catalyst, in order to produce a stream A comprising 2,3,3,3-tetrafluoropropene, HF and unreacted 2-chloro-3,3,3-trifluoropropene; and ii) in a second reactor, bringing hydrofluoric acid into contact, in the gas phase in the presence or absence of a catalyst, with at least one chlorinated compound selected from the group consisting of 1,1,1,2,3-pentachloropropane, 2,3-dichloro-1,1,1-trifluoropropane and 1,1,2,3-tetrachloropropene, in order to produce a stream B comprising 2-chloro-3,3,3-trifluoropropene, characterized in that the stream A obtained in stage i) feeds said second reactor used for stage ii); and in that stage i) is carried out at a temperature which is lower than or equal to the temperature at which stage ii) is carried out.-
