Notes:
   ¹  Only graphical results were available in this paper; the solubility c, was shown as a function of partial pressure, p₁, up to a partial pressure of 101.3 kPa showing that Henry's law was obeyed. Values of c for a partial pressure of 101.3 kPa were read from an enlarged graph by the compiler.
   ²  Calculated by the compiler.

Method/Apparatus/Procedure:
   A known quantity of solvent was charged into a thermostated saturation vessel attached to a mechanical mixer. Ethene gas admixed with argon was allowed to flow into the saturation vessel at a controlled rate. The composition of the gas was monitored by chromatography. Saturation of the solvent continued until the content of ethane entering and leaving the saturation vessel was the same. The gas analysis was by means of chromatography using a thermal conductivity detector. Samples of saturated solution were withdrawn by means of a syringe and analyzed also by chromatography but using a flame ionization detector.
