 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) C.P. grade, Eastman Chemicals, was recrystallized from alcohol to give a melting point temperature of 69.1 °C.
   (2) Purity and chemical source were not specified, was purified by distillation.

 Estimated Errors:
   Solubility: x1: ± 0.001.
   Temperature: T/K: precision ± 0.1.
