The solubility temperatures of the liquid phases were determined in ternary mixtures with a constant mass relationship of (2) and (3) as 10.0:90.0, 15.0:85.0, 20.0:80.0, 30.0:70.0, 40.0:60.0, 50.0:50.0, 70.0:30.0, and 85.0:15.0, respectively.The compositions of two and three coexistent liquid phases at 10 °C, 20 °C, 26 °C, 28 °C, and 60 °C are also presented in graphical form.
