Conditions:
Room Temp:
450.15 - 607.15
$\pu{K}$
Pressure:
1.59 - 7.65
$\pu{MPa}$
Compiler:
Methodology:
A static all-metal high-pressure autoclave was used. There was no stirring. Long equilibration times were used. The amounts of water and carbon dioxide in the liquid sample were determined by weighing. The $\ce{H2O}$ was absorbed by anhydrone and the $\ce{CO2}$ in Carbosorb.
Sample Information:
- Not stated.
- Degassed.
Measurement Errors:
Ambient temperature: Not given.
System Components:
- Carbon dioxide, $\ce{ CO2 }$; [124-38-9] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
