Method/Apparatus/Procedure:
   Constant temperature bath and a precision thermometer.
Solubilities were measured using a dynamic method. Mixtures of known concentrations were sealed in thick-walled glass ampoules and placed in a constant temperature to equilibrate. Bath temperature was slowly increased by 2 K per hour. Solubility determined by visually noting the temperature at which the last trace of solid solute  disappeared.

Source and Purity of Materials:
   (1) Purity not specified, P.O.Ch., Gliwice, Poland, was vacuum sublimed to a melting temperature of 80.25 ºC.
   (2) Initial purity not specified, Reachim, Poland, was dried over sodium carbonate and fractionally distilled to a final purity of 99.9+ %.
