Method/Apparatus/Procedure:
Two methods were used. The solubility temperatures of the liquid phases were determined by the synthetic method (Alekseev [1]) The analytical method described in Nikurashina and Mertslin [2] was used for determining equilibrium liquid phase compositions. Samples from coexisting liquid phases at equilibrium were analyzed by refractometry. No experimental details given.
Source and Purity of Materials:
- Source not specified; freshly distilled; BP = 101°C, $n_{D}^{20}$ = 1.3816.

Experimental Data
The solubility temperatures of the three liquid phases were determined in ternary mixtures with a constant mass content of (3), respectively, 30.0, 50.0, and 70.0 mass %. These data were also reported in graphical form. The solubility temperatures of the two liquid phases were determined in ternary mixtures with a constant mass relationship of (1) and (2) as 30.0:70.0, 40.0:60.0, 50.0:50.0, 60.0:40.0, 70.0:30.0, 80.0:20.0, and 90.0:10.0, respectively.
The compositions of two and three coexistent phases at 50°C are also presented in graphical form.
