PROCESS FOR PRODUCING 2,3,3,3-TETRAFLUOROPROPENE |
摘要 |
The present invention relates, in part, to the discovery that the presence of impurities in 1,1,2,3-tetrachloropropene (1230xa) results in catalyst instability during the fluorination of 1230xa to 2-chloro-3,3,3-trifluoropropene. By substantially removing the impurities, it is shown that the catalyst life is extended and results in improved operation efficiency of the fluorination reaction. Such steps similarly result in an overall improvement in the production of certain hydrofluoroolefins, particularly 2,3,3,3-tetrafluoropropene (1234yf). |
