Experimental Remarks:

   The solubility temperatures of liquid phases were determined in ternary mixtures with a constant mass relationship of (1) and (3), respectively, 10.0:90.0, 20.0:80.0, 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. These data are also presented in graphical form as isothermal curves of ternary system solubility.

    The compositions of two coexistent liquid phases at 20 °C are also presented in graphical form.

Notes:
   ^*  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; freshly distilled.
   (2) Source not specified; freshly distilled.
   (3) Source not specified; freshly distilled.

Estimated Errors:

   Temperature: Not specified.
