Title (EN) METHOD FOR SEPARATING HF FROM HF/HALOGENATED HYDROCARBON MIXTURES USING IONIC LIQUIDS
(FR) PROCÉDÉ DE SÉPARATION DE FLUORURE D'HYDROGÈNE DE MÉLANGES FLUORURE D'HYDROGÈNE/HYDROCARBURES HALOGÉNÉS AU MOYEN DE LIQUIDES IONIQUES
Abstract:
(EN) The present invention relates to an ionic liquid comprised of a salt, the anion of which is C1-, F-, and (HF)nF- (n = 1.0 - 4.0), or combination thereof. In another embodiment, the present invention relates to a process of separating HF from a first mixture comprised of at least one halogenated hydrocarbon and HF which comprises contacting the mixture with an ionic liquid comprised of a salt, the anion of which is C1-, F-, and (HF)nF- where n is a positive number ranging from 1 to 4, inclusive 4.0), to form a second mixture comprised of HF, halogenated hydrocarbon and said ionic liquid, extracting a solution comprising HF therefrom, and recovering HF therefrom.
(FR) L'invention concerne un liquide ionique constitué d'un sel dont l'anion est C1-, de F- et de (HF)nF- (n = 1,0 - 4,0), ou d'une combinaison de ceux-ci. Dans un autre mode de réalisation, l'invention concerne un procédé de séparation de fluorure d'hydrogène (HF) d'un premier mélange constitué d'au moins un hydrocarbure halogéné et de HF. Ce procédé consiste : à mettre en contact le mélange avec un liquide ionique constitué d'un sel dont l'anion est C1-, de F- et de (HF)nF-, n étant un nombre positif compris entre 1 et 4, 4,0 compris), de sorte à former un deuxième mélange constitué de HF, d'un hydrocarbure halogéné et dudit liquide ionique ; à extraire de ce mélange une solution contenant HF ; et à récupérer HF de cette solution.
