We simulate the diffusion-driven dissolution or growth of a single-component liquid drop embedded in a continuous phase of a binary liquid. Our theoretical approach follows a diffuse-interface model of partially miscible ternary liquid mixtures that incorporates the non-random, two-liquid (NRTL) equation as a submodel for the enthalpic (so-called excess) component of the Gibbs energy of mixing,...

Liquid-liquid equilibrium data were measured and analyzed for two ternary systems (biodiesel + methanol glycerol methyl palmitate glycerol). Biodiesel, produced by the conventional chemical route at 60 °C min, using soybean oil a molar rate of 10:1 potassium hydroxide concentration (KOH) 1 wt% exhibited thermal decomposition temperatures between 100 250 ºC, reaching mass loss approximately 98.8...

Abstract To separate the azeotropic mixture n-butyl acetate and n-butanol by liquid–liquid extraction, three ionic liquids (ILs) 1-ethyl-3-methylimidazolium dihydrogen phosphate ([Emim]H2PO4), 1-butyl-3-methylimidazolium ([Bmim]H2PO4) 1-hexyl-3-methylimidazolium ([Hmim]H2PO4) were adopted as extractants. The equilibrium data for ternary mixtures (n-butyl acetate + n-butanol + [Emim]H2PO4/[Bmim]...

Isobaric vapor-liquid equilibrium measurements are reported for binary mixture of 2-Methyltetrahydrofuran and Cumene at 97.3 kPa. The data were obtained using a vapor recirculating type (modified Othmer's) equilibrium still. The mixture shows slight negative deviation from ideality. The system does not form an azeotrope. The experimental data obtained in this study are thermodynamically consist...
