PREDICTION OF LLE DATA FOR AQUEOUS MIXTURE OF PROPIONIC ACID USING HEPTYL ACETATE

(Liquid–liquid) equilibrium (LLE) data were investigated for mixtures of (water + propionic acid + heptyl acetate) at T= 298.15 K and P= 1019.0 hPa. The tie-line data were predicted by the UNIFAC method. The distribution coefficients and the separation factors for the immiscibility region are calculated to evaluate the ability of solvent to extract the acid from aqueous solution.
