 Method/Apparatus/Procedure:
   The synthetic (Alekseev) and, below 353 K, the titration methods were used. A glass device with a magnetic stirrer was filled with 5 to 10 mL of (1) then placed in a thermostat, stirred, and small amounts of (2) added until turbidity appeared. The sample was then heated to above the complete homogeneity temperature, and then cooled until turbidity reappeared. Repeated determinations were made. Above 353 K, the method of Alekseev was used. Samples, 4 to 5 g, were sealed in glass, placed in thermostat, and the solubility temperature determined as above.
