Original Measurements

Szafranski, A. M.; Wyrzykowska-Stankiewicz, D.; Int. Data Series: Sel. Data Mixtures, Ser. A 1984, 46.

Variables:

Room Temp: 302.8 - 342.2 $\pu{K}$

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. Pure Grade, Glovkhimreaktiv, Kharkov, USSR, was recrystallized thrice from methanol and zone refined.
2. Pure Grade, Inst. Chem. Przerobki Wegla, Zabre, Poland, was recrystallized thrice from methanol.

Estimated Errors:

Ambient temperature: T/K: precision ±0.1.
Mole fraction - Liquid (1): x₁: ±0.0005.
