Method/Apparatus/Procedure:
The method of measurement was not specified.
It is stated in the paper that Henry's law is obeyed. A check of the data shows that Henry's law is only very approximately obeyed.
Henry's constants, H in mm Hg/mole fraction, as determined by the authors and as calculated by the compiler are as follows:
(authors) (compiler)
t/°C 10–2H 10–2H
–20 3920 2927
0 4025 3714
20 5830 6000
35 6380 6222
50 7090 ; 7407
65 9350 13,333
Source and Purity of Materials:
- Ethene purity by gas chromatography was 99.5%.
- The solvent was washed and boiling temperature was measured at 4 mm mercury pressure as 115°C. Actual purity not determined.
Estimated Errors:
Mass concentration (m/v) (1): δx1/x1 = ±0.1 or 10% (Compiler)
Experimental Values:
Note: The solubility is expressed as 104 x1 where x1 is the mole fraction.| T (K) | T (°C) | x1 | P (mm Hg) |
