The reactions of uranium hexafluoride with hydrogen sulfide and with carbon disulfide

Article abstract of DOI:10.1021/ic50010a044

Uranium hexafluoride reacts with hydrogen sulfide at 25° to produce uranium tetrafluoride, sulfur tetrafluoride, and hydrogen fluoride. Uranium hexafluoride reacts with carbon disulfide vapor at 25° to produce uranium tetrafluoride, sulfur tetrafluoride, bistrifluoromethyl disulfide [(CF₃)₂S₂], and bistrifluoromethyl trisulfide [(CF₃)₂S₃], and at elevated temperatures the reaction also produces sulfur hexafluoride and tetrafluoromethane, CF₄. When uranium hexafluoride vapor reacts with carbon disulfide vapor at 25° in the presence of helium as a diluent, the favored perfluoroalkyl product is bistrifluoromethyl trisulfide. Uranium hexafluoride is compared with other metal fluorides with respect to their reactions with carbon disulfide.
