Solid–liquid equilibria in mixed electrolyte aqueous solution have been investigated using available thermodynamic data for solids and for aqueous electrolyte solutions. The mean spherical approximation (MSA) modified by Lu et al. [Fluid Phase Equilib. 85 (1993) 81] is used to calculate the mean ionic activity coefficients in mixed electrolyte solutions at saturation conditions. Solid–liquid eq...

the determination region of solubility of methanol with gasoline of high aromatic content was investigated experimentally at temperature of 288.2 k. a type 1 liquid-liquid phase diagram was obtained for this ternary system. these results were correlated simultaneously by the uniquac model. the values of the interaction parameters between each pair of components in the system were obtained for t...

It is often difficult to determine the solid-liquid transition by conventional simulation techniques because of the computational challenges posed by two dense phases. Hansen and Verlet [Han69] reported the first molecular simulation results for solid-liquid phase coexistence. They used a thermodynamic integration algorithm that involves the accurate evaluation of free energies. The widely used...

We have used Monte Carlo simulation and the Gibbs–Duhem integration technique to calculate temperature– composition and pressure–temperature phase diagrams for binary Lennard–Jones mixtures. We systematically explore Lennard–Jones parameter space to demonstrate how the features of these phase diagrams change as a function of diameter ratio, well-depth ratio, binary interaction parameter, and pr...

After a brief recall of the chromatographic principles, t h e different applications of gas chromatographic measurements of thermodynamic equilibria were reviewed. Gas and liquid chromatographies are now well known and elegant methods for measuring the physicochemical properties and phase equil ibrium thermodynamic constants. Although fundamentally a dynamical method and mostly known as a power...

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...
