CATALYST LIFE IMPROVEMENT IN THE VAPOR PHASE FLUORINATION OF CHLOROCARBONS

摘要

The present invention achieves a catalyst life improvement for the catalyzed vapor phase fluorination of a chlorocarbon in the presence of one catalyst and an oxygen feed. Specifically, in one non-limiting embodiment, the instant invention provides the conversion of 1,1,2,3-tetrachloropropene and/or 1,1,1,2,3-pentachloropropane to 2-chloro-3,3,3-trifluoropropene by introduction of a catalyst and oxygen co-feed to the fluorination reactor.
