Experimental Remarks:

   The solubility temperatures of the liquid phases were determined in ternary mixtures with a constant mass relationship of (1) and (2) as 17.0:83.0, 23.0:77.0, 30.0:70.0, 40.0:60.0, 50.0:50.0, 60.0:40.0, 70.3:29.7, 80.0:20.0 and 90.0:10.0, respectively.

Compositions of two coexistent liquid phases at 0 and 20 °C are also reported in graphical form.

Notes:

Method/Apparatus/Procedure:
   Two methods were used. The solubility temperatures of the liquid phase 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 anlayzed by refractometry. No experimental details given.

Source and Purity of Materials:
   (1) Source not specified; freshly distilled; b. p. = 101.3 °C, n(20 °C, D) = 1.3820, d(20 °C, 4 °C) = 1.1320.
   (2) Source not specified, freshly distilled;b. p. = 106 °C/ 98.66 kPa; n(20 °C, D) = 1.3960,d(20 °C, 4 °C) = 0.8010.
