Abstract
The present invention relates, in part, to the discovery that, during the fluorination of certain fluoroolefin starting reagents, particularly, 1,1,2,3-tetrachloropropene (1230xa), oligomerization/polymerization of such starting reagents reduces the conversion process and leads to increased catalyst deactivation. The present invention also illustrates that providing one or more organic co-feed to the fluooolefin starting stream reduces such oligomerization/polymerization and improves catalystic stability.
