    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.
    本发明部分涉及发现,在对某些氟烯烃起始试剂进行氟化过程中,特别是对1,1,2,3-四氯丙烯(1230xa)进行氟化时,这些起始试剂的寡聚化/聚合会降低转化过程并导致催化剂失活增加。本发明还说明,向氟烯烃起始流提供一个或多个有机共喂料可以减少这种寡聚化/聚合并提高催化剂稳定性。
