Abstract

Procedure for recovering hydrogen fluoride from a gas mixture that contains it, characterized in that it comprises passing said gas mixture through a mixture of an alkali metal fluoride in an inert liquid, which is maintained at a temperature such that the fluoride of hydrogen is absorbed, and then heat the mixture to a temperature sufficient to release the hydrogen fluoride.
