Original Measurements
Coon, J. E.; Auwaerter, J. E.; McLaughlin, E.; Fluid Phase Equilib. 1989, 44, 305-345.
Variables:
Room Temp: 323.6 - 385.6 $\pu{K}$
Prepared by:
Method/Apparatus/Procedure:
Constant temperature bath and a precision thermometer. Mixtures of known concentrations sealed in glass ampoules and placed in constant temperature to equilibrate. Samples were rotated while bath temperature slowly increased. Solubility determined by noting the temperature at which the last trace of solid solute disappeared.
Source and Purity of Materials:
- 99.99%, Aldrich Chemical Company, Milwaukee, Wisconsin, USA, used as received.
- 99+%, Aldrich Chemical Company, having isomer ratio of 60.6% cis and 39.4% trans, stored over molecular sieves.
Estimated Errors:
Ambient temperature: T/K: precision ±0.1.
Mole fraction - Liquid (1): x1: ±0.0003.
Components:
- Anthracene, $\ce{ C14H10 }$; [120-12-7] NIST WebBook
- Decahydronaphthalene, $\ce{ C10H18 }$; [91-17-8] NIST WebBook
