Title (EN) PROCESS FOR PREPARATION OF 2,3,3,3-TETRAFLUOROPROPENE
(FR) PROCÉDÉ DE PRÉPARATION DE 2,3,3,3-TÉTRAFLUOROPROPÈNE
Abstract:
(EN) The present invention provides an effective, selective, and industrially applicable process for producing 2,3,3,3-tetrafluoropropene. Specifically, the present invention provides a process for producing 2,3,3,3-tetrafluoropropene including reacting 2-chloro-3,3,3-trifluoropropene with hydrogen fluoride in the presence of oxygen and a catalyst comprising chromium oxide represented by the composition formula: CrOm (1.5 < m <3), or fluorinated chromium oxide obtained by fluorinating the chromium oxide.
(FR) L'invention concerne un procédé efficace, sélectif et industriellement applicable pour produire du 2,3,3,3-tétrafluoropropène. En particulier l'invention concerne un procédé pour produire du 2,3,3,3-tétrafluoropropène, consistant à faire réagir du 2-chloro-3,3,3-trifluoropropène avec du fluorure d'hydrogène en présence d'oxygène et d'un catalyseur comprenant de l'oxyde de chrome représenté par la formule de composition: CrOm (1,5 < m < 3), ou de l'oxyde de chrome fluoré obtenu par fluoration de l'oxyde de chrome.
