Реферат: The present invention relates to an ionic liquid comprised of a salt, the anion of which is C1 - , F - , and (HF) n F - (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) n F - 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.
