Method/Apparatus/Procedure:
The experimental methods were described in [1]. Water impurities in alcohol were taken into account in the measurements. Critical point of liquid-liquid equilibrium was obtained graphically by the method reported in [2].
Source and Purity of Materials:
- Source and method of preparation were reported in [1].
- Source not specified; pure grade; distilled; water concentration was analyzed by the Karl Fischer method.
- Doubly distilled.
Estimated Errors:
Ambient temperature: Not specified.
Mass concentration (m/v) (1): Not reported.
