| titleOfInvention | Process for the production of trans-1-chloro-3,3,3-trifluoropropene |
| abstract | The present invention relates to a process for the production of trans-1-chloro-3,3,3-trifluoropropene, comprising the steps of: i) providing a reactor comprising a cover, a bottom, sidewalls connecting said bottom and said cover, at least one reagent supply line and at least one line for drawing off the formed products, said reactor further containing a liquid phase A; ii) providing a stream B comprising hydrofluoric acid heated at a temperature T1 of 100 °C to 170 °C and providing a stream C comprising 1,1,3,3-tetrachloropropene and/or 1,3,3,3-tetrachloropropene; said stream B and said stream C supplying said reactor via said at least one reagent supply line; iii) reacting in said liquid phase A said stream B with said stream C in order to form stream D comprising trans-1-chloro-3,3,3-trifluoropropene. The invention is characterized in that step iii) is carried out at a temperature T2 of between 50 °C and 110 °C, and the temperature difference in absolute values between said temperature T1 and said temperature T2 is greater than 30 °C. |
