Abstract: A process for producing 2,3,3,3-tetrafluoropropene comprises i) in a first adiabatic reactor comprising a fixed bed composed of an inlet and an outlet, bringing hydrofluoric acid into contact, in the gas phase with at least one chlorinated compound in order to produce a stream A comprising 2-chloro-3,3,3-trifluoropropene, ii) in a second adiabatic reactor comprising a fixed bed composed of an inlet and an outlet, bringing the stream A into contact, in the gas phase in the presence of a catalyst, with hydrofluoric acid, to produce a stream B comprising 2,3,3,3-tetrafluoropropene. The temperature at the inlet of the fixed bed of one of said first or second reactors is between 300° C. and 400° C. The longitudinal temperature difference between the inlet and the outlet of the fixed bed of the reactor is less than 20° C.
