Liquid–liquid equilibrium data for the system water + ethanol + 2-ethyl-1-hexanol were obtained at 298.15, 308.15, and 318.15 K. Data for the binodal curves have been determined by cloud-point method and conjugate points on tie-line were obtained by correlating the refractive index of the binodal curves as a function of composition. The tie-line data at each temperatures were satisfactorily correlated using the method of Othmer and Tobias and the plait points coordinates were estimated. The experimental data were also fitted with the UNIFAC group contribution method for the activity coefficients using the isoactivity conditions as restraint equations. From the experimental results, ethanol extraction by 2-ethyl-1-hexanol appears not to depend on temperature and 2-ethyl-1-hexanol could be selected as a promissory solvent for extraction of ethanol from aqueous solutions. Keywords: liquid–liquid equilibria, ethanol extraction, water + ethanol + 2-ethyl-1-hexanol ternary system.

Equilibrium Data

Isobaric equilibrium data (P = 101.3 kPa) for the system cyclohexane-acetic acid-propionic acid have been measured by two different analytical techniques. Activity coefficients calculated by simultaneous solving of equations for the chemical and phase equilibria were subjected to a consistency test based on inaccuracies determined from the error propagation law, and were correlated by Wilson’s equation. The activity coefficients measured were compared with those calculated from binary vapour-liquid equilibrium data and with values predicted by the UNIFAC method.
