Experimental Remarks:

   The solubility temperatures of liquid phases were determined in ternary mixtures with a constant mass relationship of (1) and (2), respectively, 10.2:89.8, 19.9:80.1, 29.9:70.1, 40.1:59.9, 50.0:50.0, 60.0:40.0, 70.0:30.0, 79.9:20.1, and 90.,0:10.0. These data are also presented in graphical form. The compositions of coexistent two and three liquid phases at 28 °C, 30 °C, and 35 °C are also presented in graphical form.

   Table 1  ^*  This table was prepared by the compiler from the published curve of ternary system solubility.
   Table 2  ^*  This table was prepared by the compiler from the published curve of ternary system solubility.

Method/Apparatus/Procedure:
   Two methods were used. The solubility temperatures of liquid phases were determined by the synthetic method (Alekseev¹). The analytical method described in Nikurashina and Mertslin² was used for determining equilibrium liquid phase compositions. Samples from coexisting liquid phases at equilibrium were analyzed by refractometry. No experimental details given.
