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.
