Abstract

L'invention concerne un procédé de préparation du 1,1,1-trifluoro-2,2-dichloroéthane. On réalise la photochloration du 1,1,1 -trifluoro-2-chloroéthane, dans une zone réactionnelle avec une quantité de chlore inférieure à l'équivalent molaire en présence d'une radiation actinique pendant un temps de séjour compris entre 0,1 et 60 secondes puis on soumet l'effluent de la zone réactionnelle à une séparation dans une colonne de fractionnement. Application du procédé à l'obtention de CF3 CHCL2 pratiquement exempt de CF3 CCl 3 .
