T/K	Mole Fraction x1	Mole Fraction x2
298.8	0.288	0.712
307.0	0.353	0.647
318.1	0.470	0.530
328.7	0.604	0.396
336.7	0.723	0.277
340.0	0.776	0.224

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 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 methanol.
   (2) Purity not given, Eastman Kodak Company, was used as received.

Estimated Errors:

   Temperature: T/K: precision ± 0.1. x₁: ± 0.0002. (compiler).
