Zusammenfassung:Embodiments of methods and apparatuses for purifying phosphorus pentafluoride are provided. The method comprises the step of contacting a feed stream comprising phosphorus pentafluoride and impurities with anhydrous hydrogen fluoride. The anhydrous hydrogen fluoride reduces the impurities from the feed stream to form an impurity-depleted phosphorus pentafluoride effluent.
