Conditions:

Room Temp: 292 - 415 $\pu{K}$

Compiler:

V.P. Sazonov

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:
  1. Source not specified; pure grade reagent; dried and twice distilled in a glass packed column; $n_{D}^{20}$ = 1.3820, $d_{4}^{20}$ = 1.1381.
  2. Source not specified; analytical purity; dried and twice distilled under vacuum.
  3. Source not specified; pure grade reagent; dried and fractionated through a laboratory column; $n_{D}^{20}$ = 1.4263, $d_{4}^{20}$ = 0.7785
Measurement Errors:

Ambient temperature: ±0.1 K.

Experimental Data

The temperatures of phase transitions were determined in ternary mixtures with a constant mass content of (3), respectively, 2.0, 5.0, 10.0, 20.0, 40.0, and 60.0 mass %, and also in ternary mixtures with a constant mass relationship of (1) and (2), respectively 45.0:55.0, 65.0:35.0, and 75.0:25.0. L1 nitromethane-rich phase; L2 ethanediol-rich phase; L3 cyclohexane-rich phase. The phase which is being dissolved is indicated in the table.
