Abstract | A process for the production of trans-1-chloro-3,3,3-trifluoropropene comprises 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 products formed, said reactor further containing a liquid phase A; ii) providing a stream B comprising hydrofluoric acid heated to a temperature T1 of from 100° C. to 170° C. and providing a stream C comprising 1,1,3,3-tetrachloropropene and/or 1,3,3,3-tetrachloropropene; stream B and stream C supplying said reactor via said at least one reagent supply line; iii) reacting, in liquid phase A, stream B with stream C to form a stream D comprising trans-1-chloro-3,3,3-trifluoropropene. Step iii) is carried out at a temperature T2 of between 50° C. and 110° C., and the temperature difference between temperature T1 and temperature T2 is greater than 30° C. |
