Notes:
   Table 2  ^*  The compilers extracted these data from the published graphs.

Method/Apparatus/Procedure:
   Two methods were used. The solubility temperatures are determined by the synthetic method. The analytical method was used for determining of equilibrium liquid phase composition. Samples from coexisting liquid phases at equilibrium were analyzed by refractometry. No experimental details given.

Source and Purity of Materials:
   (1) Source not specified; pure grade reagent; distilled.
   (2) Source not specified; pure grade reagent; distilled.
   (3) Source not specified; pure grade reagent; distilled.

Estimated Errors:
   Solubility: Not specified.
   Temperature: Not specified.
