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.

Experimental Data
The solubility temperatures of the liquid phases were determined in ternary mixtures with a constant mass content of (2), respectively 35.0, 55.0, 65.0, and 75.0 mass % and also in ternary mixtures with constant mass relationship of (1) and (3) as 19.4:80.6, 27.7:72.3, 39.1:60.9, 49.0:51.0, 60.10:39.9, 70.3:29.7, 79.3:20.7, and 90.0:10.0, respectively.
