Liquid-Liquid Equilibria for Ternary Mixtures Containing Vegetable Oils, Methanol, and Cosolvents

Liquid-Liquid Equilibria for Ternary Mixtures Containing Vegetable Oils, Methanol, and Cosolvents

The liquid-liquid equilibrium (LLE) phase boundaries were determined experimentally for the ternary systems containing refined sunflower oil, methanol, and one of ten potential cosolvents at 308.2 K under atmospheric pressure by using cloud point method. n-Butylamine was found to be one of the best cosolvents, which could substantially enhance the miscibility between the oil and methanol. The L...

Ternary Liquid–Liquid Equilibria for Mixtures of {Ionic Liquid + Thiophene or Benzothiophene + Heptane} at T = 308.15 K

In this work, the desulfurization ability of alkyl-piperidinium-based and phosphonium-based ionic liquids (ILs) for (thiophene or benzothiophene + heptane) mixtures are studied. With this aim, ternary liquid-liquid phase equilibrium data (LLE) have been obtained for mixtures of {IL (1) + thiophene, or benzothiophene (2) + heptane (3)} at T = 308.15 K and p = 101.33 kPa. For this study 1-pentyl-...

Prediction of Liquid-Liquid Equilibria of Binary Systems Containing Alcohols Using EoS-GE Models

Phase Separation of Viscous Ternary Liquid Mixtures

In this work we study the demixing of ternary liquid mixtures. Our theoretical model follows the standard diffuse interface model, where convection and diffusion are coupled via a body force, expressing the tendency of the mixture to minimize its free energy. This driving force induces a material flux which, in most cases, is much larger than that due to pure molecular diffusion. Here we model ...

An Analytical Equation of State for Saturated Liquid Refrigerant Ternary Mixtures

In this work an analytical equation of state has been employed to calculate the PVT properties ofternary refrigerant mixtures. The theoretical EoS is that of Ihm, Song and Mason, which is based onstatistical-mechanical perturbation theory, and the two constants are enthalpy of vaporization ΔHvapand molar density ρnb, both at the normal boiling temperature. The following three temperaturedepende...
