Abstract

L'invention concerne un procédé de préparation du 1,2-dichloréthane par oxychloration de l'éthylène à l'aide de gaz chlorhydrique et d'un gaz contenant de l'oxygène moléculaire en phase gazeuse, à température élevée et en présence d'un catalyseur à lit fluidisé au chlorure de cuivre-II sur un support, dans lequel on refroidit sous pression les gaz de réaction en deux stades de condensation, on évacue ensuite le 1,2-dichloréthane condensé et on recycle la majeure partie des gaz de départ non convertis et des gaz inertes. Le procédé selon l'invention est plus particulièrement caractérisé en ce que, dans un troisième stade de condensation, on refroidit les gaz de réaction à une température comprise entre 5 et 18 degrés C dans une mesure juste suffisante pour retenir 0,5 à 3,0 % en volume de 1,2-dichloréthane et on mélange directement, en amont du réacteur, le gaz de recyclage avec la quantité d'oxygène pur nécessaire pour remplacer l'oxygène consommé et retablir une teneur en oxygène de 12 à 25 % en volume.
