Original Measurements

Warner, J. C.; Scheib, R. C.; Svirbely, W. J.; J. Chem. Phys. 1934, 2, 590-594.

Variables:

Room Temp: 301.1 - 325.5 $\pu{K}$

Prepared by:

W.E. Acree, Jr.

Method/Apparatus/Procedure:

Constant temperature bath and a precision thermometer. Mixtures of known concentrations sealed in glass tubes 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. Measurements repeated several times to verify results.

Source and Purity of Materials:

1. Purity not specified, Eastman Kodak Company, Rochester, New York, USA, was recrystallized several times from alcohol.
2. Thiophene free, Eastman Kodak Company, was dried over calcium chloride and distilled shortly before use.

Estimated Errors:

Ambient temperature: T/K: precision ±0.1.
Mole fraction - Liquid (1): x₁: ±0.002. (compiler).
