Liquid-vapor equilibria in the system UF/sub 6/-ClF/sub 3/ at 67 deg C and (in part) 84 deg C have been investigated. Complete miscibility is exhibited at the lower temperature over the whole composition range and at the higher temperatare up to 0.565 mol. fraction Hex. Mixtures with smaller quantities of Hex than this were not studied at the higher temperature due to the high pressure hazard. Liquid vapor equilibria in the system UF/sub 6/-BrF/sub 5/ at 68 and 80 deg C were investigated. The components are completely miscible and the results indicate the formation of an azeotrope of maximum total vapor pressure of approximate composition 0.1 mol. fraction Hex. An attempt has been made to study liquid-vapor equilibria in the system UF/sub 6/-BrF/sub 3/ at 82 deg C. The incomplete results obtained indicate that it should be possible to separate these compounds by simple distillation. (auth)
