Conditions:
Room Temp:
323.15 - 423.15
$\pu{K}$
Pressure:
10 - 80
$\pu{MPa}$
Compiler:
Methodology:
A static method with sampling and analysis of the liquid phase was used. To attain equilibrium, the cell was gently rocked over 160 degrees.
(The authors also did measurements at 298.15 K, but as the experimental pressures are greater than the $\ce{CO2}$ vapor pressure at that temperature, the data at 298.15 K are not given here.)
Sample Information:
- Not stated.
- Not stated.
Measurement Errors:
Mass concentration (m/v) (1): δS = ±(3-5)% (by authors)
System Components:
- Carbon dioxide, $\ce{ CO2 }$; [124-38-9] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
