چکیده:

Liquid–liquid equilibrium data for the (water + Formic acid + 2-ethyl-1-hexanol) ternary system were determined at T = (318.2) K in ambient pressure. This ternary system exhibits type-2 behavior of LLE. Distribution coefficients and separation factors were measured to evaluate the extracting capacity of the solvent. The consistency of the experimental tie-line data was determined through the Othmer–Tobias and Bachman equations. The raw experimental data were correlated using the (UNIQUAC) model. The average root-mean-square deviation between the experimental and calculated mass fractions was 0.9854%.
