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; H
2
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:
(1) Source not specified; purified in the laboratory; b.p.=78.3 ±0.1°C, n(20°C,D)=1.3614; the properties were in agreement with literature data, purity was checked by glc analysis.
(2) Source not specified; purified in the laboratory; b.p.=110.7 ±0.1°C, n(20°C,D)=1.4969; the properties were in agreement with literature data, purity was checked by glc analysis.
(3) Double distilled.
Estimated Errors:
Solubility: Not reported.
Temperature: Pressure ±0.1 Torr.
