Methodology:
The apparatus utilized a continuous flow of deaerated solvent injected into a glass absorption spiral tube by means of a calibrated syringe pump. The mixed solvent was prepared volumetrically then deaerated and a sample analyzed by a density measurement. A mercury lift device was used for continuously adjusting the residual volume at constant pressure in a gas storage burette. Solvent injection and gas consumption rates were used to calculate solubilities. This paper also includes solution densities and refractive indices as well as ethene molecular diffusivities in the solutions.
Sample Information:
- Ethene was CP grade from Matheson with minimum purity of 99.5 mole%. Molar volume used at 298.15 K and 101.325 kPa was 24, 326 mL/mole.
- 1-Butanol was from Fisher; purity 99.0 mole%.
- 1,2-Ethanediol was from Fisher; purity 99.8 mole%
Measurement Errors:
Ambient temperature: δT/K = ±0.05
Mass concentration (m/v) (1): δz3 = ±0.001
δx1/x1 = ±0.02
Pressure: δP/P = ±0.01
