311.7	0.2075	0.7925
322.8	0.2695	0.7305

343.0	0.4334	0.5666
356.3	0.5728	0.4272

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.

Source and Purity of Materials:
   (1) 99.6 %, Aldrich Chemical Company, Milwaukee, Wisconsin, USA, was passed over an activated alumina column and then recrystallized from solution.
   (2) 99.6+ %, Aldrich Chemical Company, was stored over molecular sieves to remove trace water.

Estimated Errors:

   Temperature: T/K: precision ± 0.1. x₁: ± 0.0003 (compiler).
