Conditions:
Room Temp: 293 - 373 $\pu{K}$

Methodology:
The analytical method was used. Composition of samples was determined by GLC analysis with 2-propanol as in inert standard. (Column: 1.8 m x 5 mm internal diameter, 10% squalane on polichromom, temp. 130 °C, $\ce{H2}$-9 L/h). Solubility at 293 K was determined by Alekseev's method; at boiling point-in the apparatus reported in [2]. The description of the method was taken from [1]. Three liquid phases in equilibrium were observed in the system.
Sample Information:
- Source not specified, "chromatographic purity"; used as received; $n_{D}^{20}$ = 1.5401, BP = 205.20°C; the same as in [1].
- Source not specified; used as received; $n_{D}^{20}$ = 1.3877, BP = 98.4°C.
- Doubly distilled; the same as in [1].
Measurement Errors:
Ambient temperature: Concentration ±0.5% of glc analysis, Ref. 1.
Mass concentration (m/v) (1): Not reported.
