Abstract: A process for making 2,3,3,3-tetrafluoropropene (HFO-1234yf) includes providing a composition including 2-chloro-1,1,1,2-tetrafluorepropane (HCFC-244bb) to a reactor including a heater surface at a surface temperature greater than about 850° F. (454°C), and then bringing the composition into contact with the heater surface for a contact time of less than 10 seconds to dehydrochlorinate a portion of the HCFC-244bb to make HFO-1234yf.

Abstract: The present invention relates, in part, to the discovery that, during the fluorination of certain fluoroolefin starting reagents, oligomerization/polymerization of such reagents reduces the conversion process and leads to increased catalyst deactivation. The present invention also illustrates that vaporizing such starting reagents in the presence of one or more organic co-feed reduces such oligomerization/polymerization and improves catalytic stability.
