Gas mixtures which comprise acids like HF, HCl or HBr and other constituents, especially gas mixtures which comprise or consist of carboxylic acid fluorides, C(O)For phosphorous pentafluoride and HCl and optionally HF, can be separated by ionic liquids. The process is performed reversibly. Ionic liquids are applied the anion of which corresponds to a stronger acid than the acid to be removed. Highly purified products, for example, highly purified carbonyl fluoride can be obtained.

Reversible water-free process for the separation of acid-containing gas mixtures

A process for removing water and/or carbon compounds from hydrogen fluoride by contacting the hydrogen fluoride to be purified with elemental fluorine.

Removal of water and/or hydrocarbons from hydrogen fluoride

A process for preparing ultrapure hydrogen fluoride by contacting impure hydrogen fluoride with elemental fluorine in the presence of metal fluorides. The ultrapure hydrogen fluoride which can be obtained can be used in electronics or optics or for preparing fluorine-containing organic or inorganic compounds or ultrapure hydrofluoric acid.
