Title (EN) METHOD OF HYDRODECHLORINATION TO PRODUCE DIHYDROFLUORINATED OLEFINS
(FR) PROCÉDÉ D'HYDRODÉCHLORATION POUR PRODUIRE DES OLÉFINES DIHYDROFLUORÉES
Abstract:
(EN) Disclosed is a process for the preparation of fluorine-containing olefins comprising contacting a chlorofluoroalkene with hydrogen in the presence of a catalyst at a temperature sufficient to cause replacement of the chlorine substituents of the chlorofluoroalkene with hydrogen to produce a fluorine-containing olefin, wherein said catalyst is a composition comprising chromium, nickel and optionally an alkali metal selected from potassium and cesium. Also disclosed are catalyst compositions for the hydrodechlorination of chlorofluoroalkenes comprising copper, nickel, and an alkali metal selected from potassium and cesium, and methods of making such catalysts.
(FR) L'invention porte sur un procédé de préparation d'oléfines contenant du fluor comprenant la mise en contact d'un chlorofluoroalcène avec de l'hydrogène en présence d'un catalyseur à une température suffisante pour provoquer un remplacement des substituants chlore du chorofluoroalcène par de l'hydrogène afin de produire une oléfine contenant du fluor, ledit catalyseur étant une composition comprenant du chrome, du nickel et facultativement un métal alcalin choisi parmi le potassium et le césium. L'invention porte également sur des compositions de catalyseur pour l'hydrodéchloration de chlorofluoroalcènes, comprenant du cuivre, du nickel et un métal alcali choisi parmi le potassium et le césium, et sur des procédés de fabrication de tels catalyseurs.
