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.


The pressure-temperature-composition data for liquid-vapour equilibrium in the systems carbon dioxide-ethylene and carbon dioxide-propylene are given; the former system is shown to form a series of azeotropes. The plait-point curves and critical constants for the two series of mixtures have been determined.
