摘要：
This invention achieves a catalyst life improvement for the catalyzed vapor phase reaction of 1,1,1,3,3-pentachloropropane with hydrogen fluoride to form 1-chloro-3,3,3-trifluoropropene by introducing an oxygen co-feed into the fluorination reactor. By introduction of an oxygen co-feed to the reactor feed, the catalyst life was extended a minimum of two-fold (2×).
