Method/Apparatus/Procedure:
   The cloud point method was used to find compositions along the saturation curve. The analytical method was used to describe phases in equilibrium. The ternary samples of about 50 mL were thermostated for 1 h, then the phases were separated and the compositions were determined by glc analysis.

Source and Purity of Materials:
   (1) Source not specified, "high purity" commercial samples; used as received; purity > 99 mass % by glc.
   (2) Source not specified, "high purity" commercial samples; used as received; purity > 99 mass % by glc.
   (3) Distilled.
