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.
