Notes:
   ¹  Only graphical results were available in this paper; a value of log of Henry's constant (H' ) was read from an enlarged graph by the compiler.
   ²  Henry's constant (H) and mole fraction solubility (x₁) were calculated by the compiler.

Method/Apparatus/Procedure:
   A metal cryostat was cooled with dry-ice and acetone and controlled to a temperature to ± 0.05 K.
The equilibration cell was mounted in the cryostat. The solvent was purified by fractional distillation and analyzed by chromatography. Details were not given.

Source and Purity of Materials:
   1. Ethene purity was stated to be 99.9%.
   2. 2-Propanone was distilled and analyzed by chromatography. Actual purity not given.

Estimated Errors:
   Solubility: δx₁/x₁ = ± 0.01 (Authors)
   Temperature: δT/K = ± 0.05
