Zusammenfassung:A composition including at least 98 mol % of (E/Z)-1-chloro-3,3,3-trifluoropropene and less than 0.5 mol % of coproducts selected from 1,3,3,3-tetrafluoropropene and 1,1,1,3,3-pentafluoropropane. A composition obtained from a process for producing 1-chloro-3,3,3-trifluoropropene, including the step i) of contacting hydrofluoric acid (HF) in a reactor with a starting composition including at least one of the chloro compounds selected from 1,1,3,3-tetrachloropropene (1230za), 1,3,3,3-tetrachloropropene (1230zd) and 1,1,1,3,3-pentachloropropane (240fa), or a mixture thereof, to produce a stream A including 1-chloro-3,3,3-trifluoropropene (1233zd), wherein the step i) is carried out in a low-HF liquid phase.
