Onda, K.; Sada, E.; Kobayashi, T.; Kito, S.; Ito, K.; J. Chem. Eng. Jpn. 1970, 3, 18-24.
Variables:
Ambient temperature: 298.15 K
Pressure: 101.325 kPa
Amount concentration (2): C2/mol L-1 = 0 - 3.632
Prepared by:
Method/Apparatus/Procedure:
Solutions made up by weight and density measured but not reported in paper. Equilibrium established between a measured volume of gas and a measured amount of gas-free liquid in a cell fitted with a magnetic stirrer. Amount of gas absorbed estimated from change in volume of gas. Details in source.
Source and Purity of Materials:
- Commercial sample, minimum purity 99.8 mole%.
- Analytical grade.
- Distilled and degassed.
Estimated Errors:
Ambient temperature: δT/K = ±0.2 (estimated by compiler)
Mass concentration (m/v) (1): δα = ±2% (estimated by the compiler)
Experimental Values:
Note: P = 1 atm = 101.325 kPa = 1.01325 bar| T (K) | C2 (mol/L) | α (cm3(g) cm-3(l) atm-1) |
