Methodology:
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.

Experimental Data
The solubility temperatures of the liquid phases were determined in ternary mixtures with a constant mass relationship of (1) and (2) as 10.0:90.0, 20.0:80.0, 30.0:70.0, 40.0:60.0, 50.0:50.0, 60.0:40.0, 69.3:30.7, 85.0:15.0, 90.0:10.0, 91.0:9.0, 92.5:7.5, 95.0:5.0 and 97.5:2.5, respectively.
The compositions of coexistent two and three liquid phases at 0°C, 5°C, 7°C, and 40°C are also reported in graphical form.
