Studying phase equilibrium liquid-vapor in the system UF/sub 6/-BRF/sub 3/ with 343.15 and 353.15 K

The given paper studies the liquid-vapor phase equilibrium in the system UF₆-BrF₃ under temperatures of 343.15 and 353.15 K. For the experiments, bromine trifluoride and industrial uranium hexafluoride were used. Cleaning UF₆ and BrF₃ from HF was performed by long low-temperature vacuum distillation laws of phase equilibria. Thus, the thermodynamic analysis of experimental and calculated data by the phase equilibriums liquid-vapor in the system UF₆-BrF₃ at the temperatures 343.15 K and 353.15 K revealed their conformity to main laws of phase equilibriums. Obtained experimental data show the capability of dividing the considered system into pure components by the methods of distillation and rectification.
