Abstract

L'invention concerne un procédé pour l'obtention du 1,1-difluoroéthylène par chloration photochimique du 1,1-difluoroéthane en 1,1-difluoro-1-chloroéthane et chauffage ultérieur à 550-750 degrés C. Dans ce procédé, le difluoroéthane utilisé provient de la fluoration catalytique de l'acétylène et contient encore des impuretés qu'il n'est pas nécessaire de séparer. Application : fabrication de 1,1-difluoroéthylène.
