Method/Apparatus/Procedure:
The conventional gas chromatographic technique 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 no allowance was made for surface adsorption.
Source and Purity of Materials:
- No details given.
Estimated Errors:
Ambient temperature: δT/K = ±0.05
Mass concentration (m/v) (1): δH = ±2%
Components:
- Ethene, $\ce{ C2H4 }$; [74-85-1] NIST WebBook
- Benzene, $\ce{ C6H6 }$; [71-43-2] NIST WebBook
