Abstract
A production process for the production of E-1-chloro-3,3,3-trifluoropropene, the process including at least one stage during which 1,3,3,3-tetrachloropropene reacts with anhydrous hydrofluoric acid in the liquid phase, in the absence of a catalyst, with an HF/1,1,3,3-tetrachloropropene molar ratio between 3 and 20 inclusive, at a temperature between 50° C. and 150° C. inclusive and an absolute pressure of between 1 and 20 bar inclusive.
