Method/Apparatus/Procedure:
The analytical method was used. The equilibrium was investigated at the boiling temperature at 760 Torr. The samples were taken for GLC analysis through heated capillaries. Analysis: column 2 m long and 4 mm diameter filled with polichrom with 15% polyethyleneglycoladipinate; 100 °C; $\ce{H2}$ 100 mL/min; internal standard and homogenizer-acetone. Boiling temperatures of the two-phase mixture at 760 Torr. were estimated from the authors' graph.
Source and Purity of Materials:
- Source not specified; purified in the laboratory; BP = $\pu{78.3 \pm 0.1^{\circ}C}$, $n_{D}^{20}$ = 1.3614; the properties were in agreement with literature data, purity was checked by GLC analysis.
- Source not specified; purified in the laboratory; BP = 110.7±0.1°C, $n_{D}^{20}$ = 1.4969; the properties were in agreement with literature data, purity was checked by GLC analysis.
- Double distilled.
Estimated Errors:
Ambient temperature: Pressure ±0.1 Torr.
Mass concentration (m/v) (1): Not reported.
Components:
- Ethanol, $\ce{ C2H6O }$; [64-17-5] NIST WebBook
- Toluene, $\ce{ C7H8 }$; [108-88-3] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
