Patent ID: 11286221

Abstract:
The present invention relates to a process for producing 1-chloro-3,3,3-trifluoropropene (HCFO-1233zd), comprising: i) providing a stream A1 comprising HF, a stream A2 comprising 1,1,3,3-tetrachloropropene and/or 1,3,3,3-tetrachloropropene, and a reactor containing a liquid phase, ii) in said reactor, contacting, in said liquid phase, said stream A1 comprising HF with said stream A2 comprising 1,1,3,3-tetrachloropropene and/or 1,3,3,3-tetrachloropropene under conditions which are sufficient to produce a stream C comprising 1-chloro-3,3,3-trifluoropropene, HF and HCl, iii) recovering said stream C, characterized in that said reactor is provided with means for stirring said liquid phase so as to keep the temperature of said liquid phase substantially constant during step ii).
