Experimental Remarks:

   The solubility temperatures of the liquid phases were determined in ternary mixtures with a constant mass content of (1), respectively, 55, 65, and 75 mass %, and also in ternary mixtures with a constant mass relationship of (2) and (3) as 16:84, 32:68, 47:53, 61:39, 75:25, and 89:11, respectively. These data were also reported in graphical form as isothermal curves of ternary system solubility.
