T/KChemical NameHenry's law constant, K [atm]Henry Constant NoteMole Fraction (x1)x1 Note
298.15Hexadecane42.8HC2H40.0234* at 1 atm
323.15Heptadecane52.0HC2H40.0192* at 1 atm
 Notes:
   *  *Calculated by compiler assuming a linear function of HC2H4. vs xC2H4, i.e. xC2H4 (1 atm) = 1/HC2H4.

 Method/Apparatus/Procedure:
   A conventional gas-liquid chromatographic unit fitted with a thermal conductivity detector was used. The carrier gas was helium. The value of Henry's law constant was calculated from the retention time. The value applies to very low partial pressures of gas and there may be a substantial difference from that measured at 1 atm. pressure. There is also considerable uncertainty in the value of Henry's constant since surface adsorption was not allowed for although its possible existence was noted.

 Source and Purity of Materials:
   (1) L'Air Liquide sample, minimum purity 99.9 mole per cent.
   (2) Touzart and Matignon or Serlabo sample, purity 99 mole per cent.

 Estimated Errors:
   Solubility: δH/atm = ± 6% (estimated by compiler)
   Temperature: δT/K = ± 0.1 (estimated by compiler)
