Method/Apparatus/Procedure:
All experimental details are given in an Appendix deposited in a Documentation Centre rather than in the original paper. The solubility of (1) in (2) was measured by gas chromatography, whilst that of (2) in (1) was measured by Karl Fischer titration.
Source and Purity of Materials:
- No details given.
- No details given.
Estimated Errors:
Ambient temperature: not stated.
Mass concentration (m/v) (1): ±5% relative; repeatability of replicable analyses.
Pressure: ±1%; type or error not stated.
Components:
- Benzene, $\ce{ C6H6 }$; [71-43-2] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
Experimental Data
The three phase critical point was reported to be 541.7K, 9.42 MPa and x1 = 2.528 × 10-2 (10.1 g(1)/100 g sln, compiler).
The authors are also report equations to their own and literature data over the range 273-542K, viz.
ln x1 = -170.04018 + 6922.912/T + 24.398795 lnT
ln x2 = -1.64055 - 2029.41/T + 0.00900544 T
