Experimental Values:
Note: The solubility temperatures of the liquid phases were determined in ternary mixtures with a constant mass content of (2), respectively, 15.0, 35.0, and 55.0 mass % and also in ternary mixtures with a constant mass relationship of (1) and (3) as 15.0:85.0, 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, and also in ternary mixtures with a constant mass relationship of (1) and (2) as 56.0:44.0, respectively. Numerical data were derived by compiler from graphs in the original paper.
