Room Temp:
323.15 - 423.15
$\pu{K}$
Pressure:
0.25 - 1.54
$\pu{MPa}$

Methodology:
Single pass flow apparatus. Ethene allowed to flow through solvent for 3 to 5 hours. Liquid sample withdrawn and analysed by stripping out ethene and measuring amount volumetrically. Solvent in sample estimated gravimetrically.
Sample Information:
- Purity 99.93 mole%.
- BP = 80°C; MP = 54°C; $d_{4}^{20}$ = 0.8796; $n_{D}^{20}$ = 1.5010.
Measurement Errors:
Ambient temperature: δT/K = ±0.5 (estimated by the compiler)
Mass concentration (m/v) (1): δxC2H4 = ±0.001 (estimated by compiler)
Pressure: δP/105Pa = ±0.1 (estimated by compiler)
System Components:
- Ethene, $\ce{ C2H4 }$; [74-85-1] NIST WebBook
- Benzene, $\ce{ C6H6 }$; [71-43-2] NIST WebBook
