Experimental Remarks:

   The solubility temperatures of liquid and solid phases were determined in ternary mixtures with a constant mass relationship of (1) and (2), respectively, 60.0:40.0, 70.0:30.0, and 80.0:20.0, and also in ternary mixtures with a constant mass relationship of (2) and (3), respectively, 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. These data are also presented in graphical form.

The compositions of two coexistent liquid phases at 23 °C are also presented in graphical form.

Notes:
   Table 1  ^*  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.

Source and Purity of Materials:
   (1) Source not specified; purified; b. p. = 101.3 °C; n(20 °C, D) = 1.3820, d(20 °C, 4 °C) = 1.1320.
