ABSTRACT
(Liquid + liquid) equilibrium (LLE) data for (water + acetic acid + 2-ethyl-1-hexanol) were measured at atmospheric pressure in the temperature range of (298.2 to 313.2) K. The UNIFAC model was used to predict the observed LLE data with a root-meansquare deviation value of 2.03%. A high degree of consistency of experimental data was obtained using the Othmer?Tobias correlation. The solubility of water in 2-ethyl-1-hexanol was measured at different temperatures.
