This work reports saturated-phase densities for the CO2 + methylcyclohexane system at temperatures between 298 and 448 K pressures up to critical pressure. The were measured with a standard uncertainty of <1.5 kg·m–3 fitted along isotherms recently developed nonlinear empirical correlation an absolute average deviation (ΔAAD) about 1.5 kg·m–3. also allowed estimation pressure density each tempe...

In this work, new experimental data on thermodynamic properties of ionic liquid (IL) aqueous solutions are presented. The (vapor + liquid) phase equilibria, density, and dynamic viscosity binary mixtures composed N,N-diethyl-N-methylammonium bromide ([NH,1,2,2][Br]), or methanesulfonate ([NH,1,2,2][CH3SO3]) water presented as functions temperature composition. Both ILs were synthesized specific...

This study reports liquid–liquid equilibrium (LLE) and liquid–liquid–liquid (LLLE) data for binary (phenol + n- dodecane, or n -hexadecane) ternary (water phenol systems measured under atmospheric pressure. The compositions of coexisting phases were determined with analytical cloud point methods at temperatures 298 K – 353 K. Non–Random Two–Liquid (NRTL) excess Gibbs energy model was employed t...

Abstract Bioethanol is commonly recovered from fermentation broth via distillation because it the most economical and reliable process for large-scale industrial operations. Because extraction a highly energy-efficient applicable to low-composition bio-product separation, high-performance solvents are necessary efficient bioethanol recovery. 2-Methyl pentanol, branched long-chain alcohol, which...

Accurate vapor-liquid equilibrium data have been obtained for ethyl acetate + 2-propanol and ethyl acetate + ethanol mixtures at 84.8 kPa, and the results are discussed thermodynamically. The vapor-liquid equilibrium data are correlated with redlich-Kister, Margules, Van-Laar and Ortega, equations the parameters and standard deviation of which are calculated and reported. The best correlati...

Abstract This study aims to characterize binary mixtures consisting of a liquid with dissolved gas by determining their dynamic viscosity and interfacial tension using equilibrium molecular dynamics (EMD) simulations in the temperature range between (298 573) K for solute mole fractions up 0.20. With help systematic variation solvent molecules, influence characteristics, e.g., form size, shape,...

New experimental data on the thermodynamic properties of imidazolium-based ionic liquids (ILs) and {IL + water} solutions are presented. The isothermal (vapor liquid) phase equilibrium (VLE) density binary mixtures composed 1-ethyl-3-methylimidazolium formate, [EMIM][HCOO], or acetate, [EMIM][CH3COO], water demonstrated. were measured at temperatures from 298.15 to 348.15 K over a wide IL mole ...

5 Germany 6 In a recent article, Zhang and Duan [1] presented a new potential model 7 for carbon dioxide (CO 2). It consists of three Lennard-Jones (LJ) sites to 8 account for repulsion and dispersion and three distributed partial charges to 9 describe the quadrupolar interaction. The molecular model is rigid and ro-10 tationally symmetric around the molecular axis. In that work [1], simulation...

Nitriles are strong polar compounds showing a highly non-ideal behavior, which makes them challenging systems from a modeling point of view; in spite of this, accurate predictions for the vapor-liquid equilibria of these systems are needed, as some of them, like acetonitrile (CH3CN) and propionitrile (C2H5CN), play an important role as organic solvents in several industrial processes. This work...
