Abstract
La présente invention se rapporte à un procédé de production du 2,3,3,3-tétrafluoropropène comprenant les étapes : i) dans un premier réacteur adiabatique comportant un lit fixe composé d’une entrée et d’une sortie, mise en contact de 2-chloro-3,3,3-trifluoropropène avec de l’acide fluorhydrique en phase gazeuse en présence d’un catalyseur pour produire un courant A comprenant 2,3,3,3-tétrafluoropropène, HF et 2-chloro-3,3,3-trifluoropropène n’ayant pas réagi ; et ii) dans un second réacteur adiabatique comportant un lit fixe composé d’une entrée et d’une sortie, mise en contact en phase gazeuse en présence ou non d’un catalyseur d’acide fluorhydrique avec au moins un composé chloré sélectionné parmi le groupe consistant en 1,1,1,2,3-pentachloropropane, 2,3-dichloro-1,1,1-trifluoropropane, 2,3,3,3-tétrachloropropène et 1,1,2,3-tétrachloropropène pour produire un courant B comprenant 2-chloro-3,3,3-trifluoropropène, caractérisé en ce que le courant A obtenu à l’étape i) alimente ledit second réacteur utilisé pour l’étape ii) ; la température à l’entrée du lit fixe d’un desdits premier ou second réacteurs est comprise entre 300°C et 400°C et la différence de température longitudinale entre l’entrée du lit fixe et la sortie du lit fixe du réacteur considéré est inférieure à 20°C.The present invention relates to a process for the production of 2,3,3,3-tetrafluoropropene comprising the steps: i) in a first adiabatic reactor comprising a fixed bed composed of an inlet and an outlet, contacting 2-chloro-3,3,3-trifluoropropene with hydrofluoric acid in the gas phase in the presence of a catalyst to produce stream A comprising 2,3,3,3-tetrafluoropropene, HF and 2-chloro-3, unreacted 3,3-trifluoropropene; and ii) in a second adiabatic reactor comprising a fixed bed composed of an inlet and an outlet, brought into contact in the gas phase in the presence or absence of a hydrofluoric acid catalyst with at least one chlorinated compound selected from group consisting of 1,1,1,2,3-pentachloropropane, 2,3-dichloro-1,1,1-trifluoropropane, 2,3,3,3-tetrachloropropene and 1,1,2,3-tetrachloropropene to produce a stream B comprising 2-chloro-3,3,3-trifluoropropene, characterized in that stream A obtained in step i) feeds said second reactor used for step ii); the temperature at the inlet of the fixed bed of one of said first or second reactors is between 300°C and 400°C and the longitudinal temperature difference between the inlet of the fixed bed and the outlet of the fixed bed of the reactor considered is below 20°C.
