the modified nrtl (m-nrtl) model is used to represent the excess gibbs free energy of aqueous (alcohol + electrolyte) solutions. in this work, the m-nrtl model previously developed for representation of vapor-liquid equilibria for (polymer + salt + water) systems has been extended to represent liquid-liquid equilibria of (alcohol + salt + water) systems. the proposed extension is a modified of ...

The solid–liquid equilibrium (SLE) behavior and liquid–liquid extraction (LLX) abilities of deep eutectic solvents (DESs) containing (a) thymol L-menthol, (b) trioctylphosphine oxide (TOPO) L-menthol were evaluated. distribution coefficients (KD) determined for the solutes relevant two biorefinery cases, including formic acid, levulinic furfural, acetic propionic butyric L-lactic acid. Overall,...

The comprehensive topological isomorphism of liquid–vapor, fusibility, and solubility diagrams in the proper sets variables is proven with aid van der Waals equations shift phase equilibrium. Analogues Gibbs–Konovalov Gibbs–Roozeboom laws are demonstrated ternary quaternary systems under crystallization different types solid solutions. For demonstration, reciprocal system K+,NH4+||Cl−,Br−−H2O i...

The salting out of acetonitrile from water in the presence ammonium bicarbonate was studied at atmospheric pressure 4 to 35 °C. coexisting phases were analyzed independently with H1 nuclear magnetic resonance, ion chromatography, calorimetry, and titrations. binodal region described semiempirical functions UNIQUAC thermodynamic model. critical composition ambient temperature is given by 0.02 g/...

Abstract Phase equilibria in the TiO 2 –SiO system have been studied experimentally using DTA and SEM/EDX. The thermodynamic parameters for assessed considering new experimental data of present work from literature. Moreover, miscibility liquid Al O 3 –TiO has at 2013 K air shrinkage gap 3.8 mol% demonstrated. obtained literature as well databases binary , systems used to derive description CAL...

The phase behavior of both pure systems and binary mixtures has been widely studied by molecular simulation [1], using techniques such as the Gibbs ensemble [2], Gibbs-Duhem [3] or histogram reweighing [4] algorithms. The common aim of many of these investigations is to accurately predict the phase diagram using effective intermolecular potentials, most notable the Lennard-Jones potential. In c...
