摘要： Disclosed are cover gas compositions comprising fluoroolefins for impeding the oxidation of molten nonferrous metals and alloys, such as magnesium. The cover gas compositions typically comprise C2-C6 fluoroolefins. Preferably the compounds of the cover gas composition are selected from tetrafluoropropene, pentafluoropropene and fluorochloropropene.

摘要： 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.
