(FR) PROCÉDÉ DE PRÉPARATION DE 1-CHLORO-2,2-DIFLUOROÉTHANE
Abstract: front page image
(EN)The present invention provides a process for the preparation of 1-chloro-2,2-difluoroethane comprising the following stages : (i) dehydrofluorinating 1,1,1-trifluoro-2-chloroethane to form a product stream comprising 1-chloro-2,2-difluoroethylene, optionally separation of 1-chloro-2,2-difluoroethylene from the product stream and (ii) hydrogenating 1-chloro-2,2-difluoroethylene obtained in stage (i) to give 1-chloro-2,2-difluoroethane.
(FR)La présente invention concerne un procédé pour la préparation de 1-chloro-2,2-difluoroéthane comprenant les étapes suivantes : (i) la déhydrofluoration du 1,1,1-trifluoro-2-chloroéthane pour former un flux de produit comprenant du 1-chloro-2,2-difluoroéthylène, éventuellement la séparation de 1-chloro-2,2-difluoroéthylène du flux de produit et (ii) l'hydrogénation de 1-chloro-2,2-difluoroéthylène obtenu à l'étape (i) pour obtenir 1-chloro-2,2-difluoroéthane.
