Original Measurements

McLaughlin, E.; Zainal, H. A.; J. Chem. Soc. 1959, 863-867.

Variables:

Room Temp: 311.2 - 350.8 $\pu{K}$

Prepared by:

W.E. Acree, Jr.

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:

1. Purity not given, British Drug Houses, United Kingdom, was passed over an alumina column with benzene as eluant.
2. "AnalaR", was dried over sodium wire and freshly distilled before use.

Estimated Errors:

Ambient temperature: T/K: precision ±0.1.
Mole fraction - Liquid (1): x₁: ±0.0003 (compiler).
