Variables:
Room Temp:
308.2 - 473.2
$\pu{K}$
Pressure:

$\pu{kPa}$
Prepared by:
Method/Apparatus/Procedure:
Gas chromatographic method. Solvent supported on Chromosorb P in 6m column. Gas injected as sample, helium used as carrier gas. Henry's law constant calculated from knowledge of retention time and flow rate.
Source and Purity of Materials:
- Matheson sample, purity greater than 99 mole%.
- Matheson, Coleman and Bell sample, MP: Octadecane = 27-28.5°C, Eicosane = 35-36.5°C, Docosane = 43-45°C
Estimated Errors:
Ambient temperature: δT/K = ±0.01
Mass concentration (m/v) (1): δH/atm = ±5%
Components:
- Ethene, $\ce{ C2H4 }$; [74-85-1] NIST WebBook
- Octadecane, $\ce{ C18H38 }$; [593-45-3] NIST WebBook
- Eicosane, $\ce{ C20H42 }$; [112-95-8] NIST WebBook
