    摘要： A method for treating process waste consisting of uranium hexafluoride, UF.sub.6, molybdenum hexafluoride, MoF.sub.6 and molybdenum oxytetrafluoride, MoOF.sub.4 is provided wherein the foregoing mixture is hydrolyzed in an aqueous solution of ammonium carbonate and ammonium hydroxide. The resulting mother liquor is digested at 60.degree.-80.degree. C. to drive off carbon dioxide and convert the ammonium uranyl carbonate, (NH.sub.4).sub.4 UO.sub.2 (CO.sub.3).sub.3 to ammonium diuranate, (NH.sub.4).sub.2 U.sub.2 O.sub.7. The pH is maintained above 9 to prevent premature precipitation of the molybdenum values as molybdic acid or uranyl molybdate.The ammonium diuranate which forms as a yellow solid is filtered, slurried in aqueous ammonium hydroxide, filtered and dried. The yield is quantitative. Pyrolysis results in conversion of the diuranate salt to uranium oxide, U.sub.3 O.sub.8, of suitable purity to be recycled in the uranium hexafluoride production process. The combined filtrates which contain the molybdenum values and ammonium fluoride by-product are diluted, and stirred, with 95% ethanol to precipitate white, crystalline, ammonium molybdate, (NH.sub.4).sub.2 MoO.sub.4. The ammonium fluoride remains soluble. The ammonium molybdate is filtered, dried and calcined at 600.degree. C. for 2 hours to yield molybdenum trioxide, MoO.sub.3 in >90% yield and essentially free of uranium contamination. Fluoride contamination in either of the reprocessed materials is minimal.

    摘要： Disclosed is a process for making hexafluoro-2-butyne comprising the steps of: (a) providing a composition comprising CF3CX═CXCF3, where X=halogen; and (b) treating CF3CX═CXCF3 with a dehalogenation catalyst in the presence of a halogen acceptor compound Y, where Y is not hydrogen. The halogen acceptor compound Y is a material capable of being halogenated, preferably a compound having a multiple bond, such as an alkyne, alkene, allene, or carbon monoxide. Another suitable material capable of being halogenated is a cyclopropane. A catalyst effectively transfers halogen from CF3CX═CXCF3 to the halogen acceptor compound. Since Y is not hydrogen, the formation of CF3CX═CHCF3 is greatly reduced or eliminated.
