The liquid-vapour equilibrium of the system methane-ethylene has been determined at 0, -42 , -78, -88 and -104° C over a wide range of pressures and the results are shown on a pressure-composition-temperature diagram and by a series of pressure-composition curves. The liquid-vapour equilibrium of the ternary system methane-ethane-ethylene has been determined at -104, -78 and 0° C. Values for the two binary systems methane-ethane and methane-ethylene and for the ternary system methane-ethane-ethylene are shown on a composite pressure-composition diagram.

Existing physical and thermal data relative to propane have been summarized and correlated, and some new experimental determinations of pressure-volume-temperature relationships for the liquid at low temperatures have been carried out to make good deficiencies in the literature. On the basis of the information thus obtained the entropy and enthalpy of propane have been calculated for conditions of temperature between — 80 and 200° C, and at pressures of from 0.1 to 200 atm. The results are tabulated and also presented graphically on a temperature base.

In the first section of the paper, P-V-T-x data for the systems carbon dioxide/propylene, carbon dioxide/ethylene and ethylene/propylene are presented and the phase-boundary data are discussed in terms of the laws of rectilinear diameters and corresponding states. In the second section, the thermodynamic properties of the carbon dioxide/propylene system are derived as accurately as possible, over a range of conditions including part of the critical region. For use in these calculations, suitable formulae are derived for evaluating the isothermal latent heats of the mixtures. It is found that the liquid mixtures obey the relation ( U — U 0 ) V = constant; a theoretical interpretation of this relationship is offered and, based on this theory, an equation is developed which is found to represent the variation of the enthalpy of the binary system carbon dioxide/propylene with volume and composition quite closely.

The conditions of pressure, temperature and composition under which liquid and vapour mixtures are in equilibrium must generally be determined by direct experiment. The thermodynamical relationships connecting them are applicable only when an accurate equation of state is known for the mixture in both phases, or when special circumstances permit the equations to be simplified, such as when the vapour phase may be considered as a perfect gas, or when the laws of perfect solutions may be expected to hold. At sufficiently low pressures and temperatures some such simplification may frequently be made, but at higher pressures and temperatures, more especially near or above the critical point of one of the components, the data needed to calculate the equilibrium conditions are usually unknown and difficult to ascertain. This can be made clear by deriving, as shortly as possible, the principal thermodynamical relationships for a two-phase binary system.

Good Agreement

High pressure phase behavior experimental data have been measured for the systems carbon dioxide (CO2) + 1-butyl-3-methylimidazolium hexafluorophosphate ([bmim] [PF6]) and carbon dioxide (CO2) + 1-butyl-3-methylimidazolium hexafluorophosphate ([bmim] [PF6]) + 1-amino-2-phenoxy-4-hydroxyanthraquinone (C.I. Disperse Red 60). Measurements were performed in the pressure up to 18 MPa and at the temperature (323 to 353 K). As reported in the literature, at higher concentrations of carbon dioxide the phase transition pressure increased very steeply. The experimental data for the binary and ternary systems were correlated with good agreement using the Peng-Robinson equation of state. The amount of water in phase behavior of the systems was evaluated.
