Methodology:
The gas solubility was determined using gas chromatography and employing helium as a carrier gas.
Based on the retention times and column characteristics, the Bunsen coefficient was calculated.
Sample Information:
- Sources and purities of gas and solvent not specified.
Measurement Errors:
Ambient temperature: δT/K = ±0.1
Mass concentration (m/v) (1): δp1/kPa = 2.0
δKB = ±6-8% (authors)
System Components:
- Ethene, $\ce{ C2H4 }$; [74-85-1] NIST WebBook
- 2,6,10,15,19,23-Hexamethyltetracosane, $\ce{ C30H64 }$; [111-01-3] NIST WebBook

(1) The solubility results were in the form of two equations, the first describing the temperature effect at 101.3 kPa pressure and the second the effect of pressure, to 405.2 kPa, at 313.15 K:
log KB = 568.0378 ( T/K)-1 - 1.1785 correlation coeff. = 0.9985
KB = 0.0101 p/atm + 1.2241 correlation coeff. = 0.3171 (low)
(2) The Ostwald coefficient and mole fraction solubility at 101.3 kPa were calculated by the compiler. The solvent densities were extrapolated.
