N.I. Lisov, N.V. Sazonov, V.P. Sazonov

Method/Apparatus/Procedure:

Two methods were used. The solubility temperatures of the liquid phase were determined by the synthetic method. 1 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; purity not specified; distilled; n(20°C,D) = 1.3905, d(20°C, 4°C) = 1.0525.

Experimental Values:
Note: The solubility temperatures of the liquid phases were determined in ternary mixtures with a constant mass content of (3), respectively 20.0, 30.0, 45.0 and 60.0 mass % and in ternary mixtures with constant mass relationship of (1) and (2) as 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 respectively (see Tables 1-3).
