Abstract

Hydrofluoric acid purification process, characterized in that it comprises successively the dehydration of hydrofluoric acid by reaction with fluorine, the condensation of hydrofluoric acid and the elimination of non-condensed gases, the fixation of hydrofluoric acid dehydrated on an alkaline fluoride by formation of hydrofluoric acid. a solid complex, the evacuation of unfixed impurities and the release of the purified acid by heating of said complex.
