Title (EN) ISOMERIZATION OF 1,1,3,3-TETRAFLUOROPROPENE
(FR) ISOMÉRISATION DU 1,1,3,3-TÉTRAFLUOROPROPÈNE
Abstract:
(EN) The present invention involves methods for isomerization of 1234zc. Also provided are methods for managing 1,1,3,3-tetrafluoropropene produced as a byproduct in a process for synthesizing trans-1,3,3,3-tetrafluoropropene from 245fa, wherein 1234zc is converted into trans/cis-1234ze with the help of a catalyst in the absence of HF and in an isomerization reactor, or is converted into 1234zc and/or 245fa with the help of a catalyst in the presence of HF in a separate reactor or preferably in the same reactor of 245fa dehydrofluorination.
(FR) La présente invention concerne des procédés d'isomérisation du 1234zc, un hydrocarbure fluoré. L'invention concerne également des procédés de prise en charge du 1,1,3,3-tétrafluoropropène qui est un sous-produit de la synthèse du trans-1,3,3,3-tétrafluoropropène à partir du 245fa, un autre hydrocarbure fluoré, ledit 1234zc étant converti en trans/cis-1234ze avec l'aide d'un catalyseur en absence de fluorure d'hydrogène et dans un réacteur d'isomérisation, ou en 1234zc et/ou en 245fa avec l'aide d'un catalyseur et en présence de fluorure d'hydrogène dans un réacteur séparé ou, de préférence, dans le réacteur utilisé pour la déshydrofluoration du 245fa.
