Method/Apparatus/Procedure:
Both solute and solvent were degassed before their introduction into the reaction flask where the solute was vaporized. The system was then completely immersed in a thermostat bath. The flask was shaken to attain equilibrium. Manometer readings were taken at the calibrated temperatures. The distribution constants were calculated from the monitored readings and the apparatus calibration parameters.
Source and Purity of Materials:
- Prepared by the authors. BP = 49.0°C at 732 mm Hg.
