Conditions:
Room Temp: 311 - 318 $\pu{K}$
Compiler:
Methodology:
The synthetic method (Alekseev [1]) was used. Mixtures of (1), (2) and (3) of total mass 10 g were heated with vigorous stirring to a temperature higher than the homogenization temperature, then slowly cooled until turbidity appeared. Heating and cooling cycles were repeated twice. Temperature values obtained for appearing and disappearing turbidity were averaged.
Sample Information:
- Source not specified; pure grade reagent; dried and twice distilled in a glass packed column.
- Source not specified; pure grade reagent; dried and twice distilled in a glass packed column.
- Analytical purity; dried and twice distilled under vacuum; 0.03 mass% water by the Karl Fischer analysis.
Measurement Errors:
Ambient temperature: ±0.01 K.

Experimental Data
The solubility temperatures of the liquid phases were determined in ternary mixtures with a constant mass relationship of (1) and (3) as 65.0:35.0.
