Title (EN) AN IMPROVED PROCESS FOR THE PREPARATION OF 2,3,3,3-TETRAFLUOROPROPENE
(FR) PROCÉDÉ AMÉLIORÉ POUR LA PRÉPARATION DE 2,3,3,3-TÉTRAFLUOROPROPÈNE
Abstract:
(EN) The present invention provides an improved process for preparation of 2,3,3,3- tetrafluoropropene, wherein recyclization of the reaction by-products result in equilibrium between feed and outlet composition.
(FR) La présente invention concerne un procédé amélioré de préparation de 2,3,3,3-tétrafluoropropène, la recirculation des sous-produits de réaction résultant en équilibre entre la composition d'alimentation et de sortie.
