Description

Liquid-liquid equilibrium (LLE) data for the system of (water+formic acid+2-ethyl-1-hexanol) were experimentally determined at T=(298.2, 308.2, 318.2, and 328.2) K and atmospheric pressure. A type-2 LLE was obtained for this ternary system. The influence of temperature on the equilibrium characteristics was found to be small at the temperatures studied. Distribution coefficients and separation factors were calculated over the immiscibility regions. The experimental tie-line data were correlated using the UNIQUAC model. The values of the interaction parameters between each pair of the components were obtained for this thermodynamic model. The root mean square deviation (RMSD) between the observed and calculated mass fractions was 0.61%
