Liquid-Liquid Equilibrium (LLE) data are measured for the ternary mixtures of water + 1-butanol + butyl acetate and quaternary mixtures of water + 1-butanol + butyl acetate + glycerol at atmospheric pressure at 313.15 K. In addition, isothermal vapor–liquid–liquid equilibrium (VLLE) data are determined experimentally at 333.15 K. The region of heterogeneity is found to increase as the hydrophil...

The equilibrium states of vapor and liquid coexistent phases in contact with a solid surface are studied at the nanoscale by molecular dynamics simulations for a temperature close to the fluid triple point. The characteristics of the solid-fluid interfaces are determined when the interaction strength between the fluid and the solid varies in order to go from a situation of complete drying to th...

Several physical properties and the isobaric vapour-liquid equilibria at 101.32, 50, 30 kPa were measured for binary system consisting of acetone ionic liquid 1-ethyl-3-methyl-imidazolium acetate. Liquid-liquid equilibrium data also temperatures from 298.15 up to 328.35 K atmospheric pressure. An hourglass-shaped miscibility gap was found. The simultaneous correlation both VLE LLE regions 101.3...

Vapor-liquid equilibrium and density measurements have been performed on 1.00-5.89 m tetrabutylammonium bromide (TBAB) in mixtures of 2-propanoland water. The VLE experiments were performed using a modified Othmer still a t ambient pressure. The effect of salt on the relative volatility of 2-propanol was evaluated at molalities of 1.00,1.79, and 5.89 over the full range of solvent composition. ...

Isothermal vapour−liquid equilibrium (VLE) for four binary systems involving R1234yf (R1234yf + R134a, R152a, R1233zd(E) and R1233xf) were measured at temperatures from 278.15 to 348.15 K. The experiments conducted by means of a “static−analytic” apparatus with phase analysis via gas chromatography, resulting uncertainties 0.6 K temperature, 8 kPa pressure maximum 0.007 vapour liquid mole fract...
