The present disclosure includes various manufacturing and separation processes for the production of (Z)-1-chloro-3,3,3-trifluoropropene from (E)-1-chloro-3,3,3-trifluoropropene. The efficient separation of (Z)-1-chloro-3,3,3-trifluoropropene from unreacted (E)-1-chloro-3,3,3-trifluoropropene may allow for the ability to recycle unreacted starting materials and to maximize raw material utilization and product yields.
