Original Measurements
Alwani, Z.; Schneider, G. M.; Ber. Bunsenges. Phys. Chem. 1969, 73, 294-301.
Variables:
Room Temp:
Critical Temperature
$\pu{bar}$
Pressure:
Critical Pressure
$\pu{bar}$
Prepared by:
Method/Apparatus/Procedure:
Steel optical cell in large aluminum block furnace. Cell contents stirred by magnetically operated stirrer. Pressure measured using a steel-sheathed thermocouple. Components charged into cell and one phase-two phase boundaries observed visually. Critical properties determined from boundary envelopes.
Source and Purity of Materials:
- Analytical grade product fractionally distilled, purity 99.9 mole%.
- Distilled and degassed.
Estimated Errors:
Ambient temperature: δT/K = 0.4
Pressure: δP/P = ±0.02 (estimated by compiler)
Components:
- Benzene, $\ce{ C6H6 }$; [71-43-2] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
