Method/Apparatus/Procedure:
The apparatus and procedure are described in [1]. The equilibration device is a capillary tube 1 mm in diameter containing an internal mixer which is moved up and down by means of an external, motor driven magnet. The capillary tube is sealed in a vertical position and connected to a gas and liquid charging system, pressure gauges, as well as a volume regulator to maintain a constant pressure and to determine the volume of gas charged.
Graphs of liquid solution molar volumes are also given as a function of solution compositions, including those for critical values at high pressures.
Source and Purity of Materials:
- Ethene purity 97.5% by analysis.
- Tetrachloro-propane vacuum distilled. Actual purity not given. Density and refractive index at 20°C:
ρ = 1.4325 g cm-3,
nD = 1.4806

(1) Henry's law constants and mole fraction solubility's at 101.3 kPa were evaluated by the compiler form enlarged graphs only; there were no numerical solubility data. Henry's law was Observed to fit the data closely up to about 0.40 mole fraction ethene for all temperatures.
Phase equilibrium compositions of ethene in liquid solutions are graphically shown as a function of pressure over the complete ethene composition range to 99 mole percent ethene. Critical phenomena are reported for high concentrations of ethene at high pressures.
