Original Measurements
Choi, P. B.; Williams, C. P.; Buehring, K. G.; McLaughlin, E.; J. Chem. Eng. Data 1985, 30, 403-409.
Variables:
Ambient temperature: Temperature
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:
- 99.2%, British Drug Houses, United Kingdom, was recrystallized and then zone refined.
- Gold Label, 99.9+%, Aldrich Chemical Company, was used as received.
Estimated Errors:
Ambient temperature: T/K: precision ±0.1.
Mole fraction - Liquid (1): x1: ±0.0003.
