Abstract:

The thermodynamic similarity of phase-separating binary aqueous solutions with a lower critical solution temperature is discussed. The values of temperature and pressure at the double critical point are used as scales. An analysis of the experimental material on the phase-separation of aqueous solutions of organic compounds has discovered correlations between dimensionless thermodynamic complexes that make it possible to calculate the line of the critical points (LCP) of a solution by the data on phase-separation at atmospheric pressure. The proposed algorithm of calculation is verified by the example of the mixture water/2,6-dimethylpyridine. The calculated and the experimental data for the LCP of this solution demonstrate a satisfactory agreement.
