Abstract
The invention relates to the use of a liquid-vapor separator such as a de-entrainer to remove an unvaporized portion of a feed, e.g. 1,1,2,3-tetrachloropropene (1230xa), to a catalytic vapor phase fluorination reaction where e.g. 2-chloro-3,3,3,-trifluoropropene (1233xf) is produced. The invention extends the life of the catalyst.
