Method/Apparatus/Procedure:
The method involved measuring the pressure change in a gas reservoir of known volume. Two glass bulbs were connected by tubing fitted with a pressure transducer, gas supply and vacuum lines. The solvent (100 mL) was degassed in one of the bulbs equipped with a stirrer using liquid nitrogen. Gas was charged to a higher pressure in the second bulb and quantitatively charged into the first bulb at the appropriate temperature. The final pressure in the equilibrium flask was measured.
Source and Purity of Materials:
- Ethene, Monsanto polymerization grade, purity 99.85%.
- Hexane was from Phillips Petroleum, purity 99.0%.
Estimated Errors:
Ambient temperature: δT/K = ±0.01
Mass concentration (m/v) (1): δs/s = ±2%
Components:
- Ethene, $\ce{ C2H4 }$; [74-85-1] NIST WebBook
- Hexane, $\ce{ C6H14 }$; [110-54-3] NIST WebBook
