Methodology:
The methods were reported in [1]. The titration method was used to describe solubility of the mixtures. The third component was added to the binary homogeneous mixture until the cloudiness started to be observed. Density of the saturated mixtures was measured and put on the graphs. To obtain equilibrium ternary mixtures were stirred in thermostated vessel through several hours. After phase separation, density of each phase prepared graphs. Concentration at critical point was found by the method described in [2]. Water include in propanol was taken into account in all measurements.
Sample Information:
- Source not specified, chemical pure grade; distilled; water concentrations was determined by the Karl Fischer method.
- Source not specified; properties were the same as reported in [1].
- Doubly distilled.
Measurement Errors:
Ambient temperature: Not reported.
Mass concentration (m/v) (1): Not reported.
