T/K	Mole Fraction x1	Mole Fraction x2
290.2	0.2113	0.7887
292.0	0.2217	0.7783
296.0	0.2512	0.7488
298.2	0.2570	0.7430
301.6	0.2801	0.7199
302.8	0.2892	0.7108
308.3	0.3204	0.6796

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 visual noting the same 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 recrystallized and sublimed.
   (2) Purity not given, British Drug Houses, was dried over and distilled.

Estimated Errors:

   Temperature: T/K: precision ± 0.1. x₁: ± 3 % (relative error; compiler).
