Original Measurements

Domanska, U.; Pol. J. Chem. 1981, 55, 1715-1720.

Variables:

Room Temp: Temperature $\pu{K}$

Prepared by:

W.E. Acree, Jr.

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:

1. Purity not specified, P.O.Ch., Gliwice, Poland, was vacuum sublimed to a melting temperature of 80.25°C.
2. Initial purity not specified, P.O.Ch., 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).
