LIQUID-VAPOUR EQUILIBRIA IN THE SYSTEM URANIUM HEXAFLUORIDE-CHLORINE TRIFLUORIDE
Liquid-vapor equilibria in the system UF/sub 6/-ClF/sub 3/ at 75 C were investigated. The components are partially miscible over the composition range with mole fraction hex = 0.3--0.5 at a summation vapor pressure of 109.7 psi absolute. The summation vapor pressure over the immiscible pair of saturated solutions lies between that of pure hex and that of pure chlorine trifluoride. Analysis of samples of liquid and vapor phases for various gross compositions was carried out with a sonic analyzer, a calibration curve for known hex--nitrogen mixtures being transformed to one for hex --chlorine trifluoride mixtures after determination of the natio of the specific heats of chlorine trifluoride. At 75 C the ratio of the specific heats of chlorine trifluoride was found to be 1.255. (auth)
