PROBLEM TO BE SOLVED: To provide a continuous production method of E-1-chloro-3,3,3-trifluoropropene (E-1233zd) on an industrial scale. E-1-chloro-3,3, comprising at least one step of reacting 1,1,3,3-tetrachloropropene with anhydrous hydrogen fluoride in a liquid phase in the absence of a catalyst. Reaction to give 3-trifluoropropene (E-1233zd), which involves a recycle operation consisting of separation and purification steps of the resulting stream. [Selection diagram] None |
