Calculated liquid phase thermodynamic properties and liquid-vapor equilibria for fluorine-oxygen [FLOX] mixtures

Abstract

Liquid phase thermodynamic properties and liquid vapor equilibria of fluorine-oxygen mixtures, for which no experimental data exist, have been calculated. The results are based on excess properties predicted from the Snider-Herrington equations, with an adjusted combining rule, and the corresponding data for the pure fluids. Mixtures considered are 0. 6, 0. 7, 0. 8, 0. 88, and 0. 9 weight fraction of fluorine from 55 to 90K up to 70 x 10 Pa. In the compressed liquid, molar volumes, enthalpy, entropy, and constant pressure specific heat were determined. Along the saturation boundary, coexistent vapor compositions and solution vapor pressures were determined as well. Corresponding properties of pure fluorine from experimental data have also been included. Results are tabulated in both British and S.I. units.
