METHOD FOR PURIFYING FLUORINE GAS

摘要

Disclosed is a method for purifying fluorine gas by using a reaction vessel to decrease the concentration of hydrogen fluoride in crude fluorine gas obtained by means of electrolysis of a fused salt containing hydrogen fluoride in an electrolysis vessel. The method for purifying fluorine gas is characterized by the temperature in the aforementioned reaction vessel being in the temperature range above the boiling point of fluorine and below the melting point of hydrogen fluoride, and disposing a regularized filler in the aforementioned reaction vessel.
