Original Measurements
Domanska, U.; Pol. J. Chem. 1981, 55, 1715-1720.
Variables:
Ambient temperature: Temperature
Prepared by:
Method/Apparatus/Procedure:
Constant temperature bath and a precision thermometer.
Solubilities were measured using a dynamic method. Mixtures of known concentrations were sealed in thick-walled glass ampoules and placed in a constant temperature to equilibrate. Bath temperature was slowly increased by 2 K per hour. Solubility determined by visually noting the temperature at which the last trace of solid solute disappeared.
Source and Purity of Materials:
- Purity not specified, P.O.Ch., Gliwice, Poland, was vacuum sublimed to a melting temperature of 80.25°C.
- Initial purity not specified, Reachim, Poland, was dried over sodium carbonate and fractionally distilled to a final purity of 99.9+%.
Estimated Errors:
Ambient temperature: T/K: precision ±0.1. x1: to 3 significant figs. (compiler).
