 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) 99 %, Aldrich Chemical Company, Milwaukee, Wisconsin, USA, was recrystallized from toluene.
   (2) Gold Label, 99.9+ %, Aldrich Chemical Company, was used as received.

 Estimated Errors:
   Solubility: x1: ± 0.0003.
   Temperature: T/K: precision ± 0.1.
