Abstract

La présente invention concerne un procédé de production du trifluoroéthylène dans un réacteur muni d’un lit catalytique fixe comprenant un catalyseur, ledit procédé comprenant les étapes de : a) réaction du chlorotrifluoroéthylène avec de l’hydrogène en présence du catalyseur et en phase gazeuse pour produire un courant A comprenant du trifluoroéthylène ; b) traitement dudit courant A dans des conditions suffisantes pour produire un courant D 1 comprenant du 1,1,2-trifluoroéthane dans une teneur inférieure à 15% en poids sur base du poids total dudit courant D1, c) recyclage du courant D 1 à l’étape a).
