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 analyzed by refractometry. No experimental details given.

Source and Purity of Materials:
   (1) Source not specified; purity not specified;n(20 °C, D) = 1.3820, d(20 °C, 4 °C) = 1.1320.
   (2) Source not specified, purity not specified;n(15 °C, D) = 1.4085, d(15 °C, 4 °C) = 0.8129*.
   (3) Twice distilled. * Recorded as 1.8129 on original. Value corrected by compiler.
