  • Removal of dinitrogen difluoride from nitrogen trifluoride
    Patent number: 4193976
    Abstract: This invention relates to a process for purifying a nitrogen trifluoride containing atmosphere contaminated with dinitrogen difluoride. The atmosphere is purified by heating the nitrogen trifluoride atmosphere in the presence of a particulate metal capable of defluorinating dinitrogen difluoride, but inert to nitrogen trifluoride, preferably the metal being selected from the group consisting of iron, cobalt, and nickel, to a temperature of from about 300.degree.-1000.degree. F. for a time sufficient to effect defluorination of the dinitrogen difluoride.
