Thermodynamics of the Ternary Water-Salt Systems

Thermodynamics of the Ternary System

The enthalpies of mixing of the liquid mixtures of (NaB0 2 ) 2 + B 2 0 3 , N a 4 P 2 0 7 + (NaP0 3 ) 2 , (NaP0 3 ) 2 + B 2 0 3 and N a 4 P 2 0 7 + (NaB0 2 ) 2 have been measured by liquid -(liquid calorimetry. The results are discussed in terms of tentative structural models of the melts, and in terms of O 2 ion transfers from phosphorus groups to boron groups in (NaP0 3 ) 2 + B 2 0 3 and from ...

Liquid-Liquid Equilibrium for the Ternary Systems of Solvent+ m/o/p-Cresol+Water: Thermodynamic Modeling

In this study, NRTL and UNIQUAC thermodynamic models were used to predict the composition of ternary mixtures of solvents+ m/o/p-cresol+ water in organic and aqueous phases. Various solvents are used for the separation of cresols from water. In this study, methyl propyl ketone, methyl isopropyl ketone, methyl butyl ketone, and methyl isobutyl ketone solvents were investigated. Intermolecular in...

Effect of Magnetic Field on the Liquid-liquid Equilibria of (Water + Acetic Acid + Organic Solvent) Ternary Systems

The effect of magnetic field on the liquid-liquid equilibrium of two ternary systems (water + acetic acid + butyl acetate and water + acetic acid + dimethyl succinate) at 298.15 K under atmospheric pressure was investigated. The results obtained show that the strength of the magnetic field (0.02 T) affects the solubility of acetic acid in the used organic solvents. Distribution coefficients and...

Thermodynamics of Air/Water-Cycle Air-Conditioning Systems

Thermodynamics of supercooled water.

We review the available experimental information on the thermodynamic properties of supercooled water and demonstrate the possibility of modeling these thermodynamic properties on a theoretical basis. We show that by assuming the existence of a liquid-liquid critical point in supercooled water, the theory of critical phenomena can give an accurate account of the experimental thermodynamic-prope...
