Method/Apparatus/Procedure:
A metal cryostat was cooled with dry-ice and acetone and controlled to a temperature to $\pu{pm 0.05 K}$. 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:
- Ethene purity was stated to be 99.9%.
- Heptane was distilled and analyzed by chromatography. Purity not specified.
- Methylbenzene was distilled and analyzed by chromatography. Purity not specified.
Estimated Errors:
Ambient temperature: δT/K = ±0.05
Mass concentration (m/v) (1): δx1/x1 = ±0.01 (Authors)

(1) Compositions of two-component solvent solutions are given on a solute free basis.
(2) Only graphical results were available; values of log Henry's constant (H) were read from an enlarged graph by the compiler.
(3) Values of Henry's constant (H) and mole fraction solubility (x1) were calculated by the compiler.
