Method/Apparatus/Procedure:
The analytical method was used. Composition of samples was determined by GLC analysis with 2-propanol as an 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 Alekeev's method; at boiling point in the apparatus reported in [1]. The three liquid phases in equilibrium were observed in the system.
Source and Purity of Materials:
- Source not specified, "chromatographic purity", used as received; $n_{D}^{20}$ = 1.5401, BP = 205.20°C.
- Source not specified "chromatographoic purity," used as received; $n_{D}^{20}$ = 1.3747, BP = 68.70°C.
- Doubly distilled.
Estimated Errors:
Ambient temperature: Concentration ±0.5% of glc analysis.
Mass concentration (m/v) (1): Not reported.
