Erofeeva, L. F.; Yunnikova, N. V.; Sb. Nauch. Tr.; Kuzbas. Polytekh. Inst. 26, 1-6 (1971).

Conditions:

Room Temp: 268 - 362 $\pu{K}$

Compiler:

V.P. Sazonov

Methodology:

Two methods were used. The solubility temperatures of the liquid phases were determined by the synthetic method (Alekseev [1]) The analytical method described in Nikurashina and Mertslin [2] was used for determining equilibrium liquid phase compositions. Samples from coexisting liquid phases at equilibrium were analyzed by refractometry. No experimental details given.

Sample Information:
  1. Source not specified; pure grade; distilled.
  2. Source not specified; pure grade; distilled.
  3. Twice distilled.
Measurement Errors:

Ambient temperature: Not specified.

Experimental Data

The solubility temperatures of the liquid phases were determined in ternary mixtures with a constant mass relationship of (1) and (2) as 10.0:90.0, 30.0:70.0, 50.0:50.0, 63.0:37.0, 65.0:35.0, 68.0:32.0, 70.0:30.0, and 90.0:10.0, and also in ternary mixtures with a constant mass content of (3), respectively, 1.0 mass %.
The compositions of coexistent two and three liquid phases at 2°C, 3°C, 5°C, and 20°C are also reported in graphical form.
