Notes:
   Table 1  ^*  Solubility temperatures of the solid phase.
   Table 2  ^a  The compilers extracted these data from the published graphs.

Method/Apparatus/Procedure:
   Two methods were used. The solubility temperatures of the liquid phase were determined by the synthetic method. The analytical method described in Nikurashina and Mertslin¹ 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; b. p. = 114°C, n(20°C,D) = 1.3910, d(20°C, 4°C) = 1.0520.
   (2) Source not specified; purity not specified; n(20°C,D) = 1.4315, d(20°C, 4°C) = 1.1550.
