Abstract:
In this study the correlation of phase equilibrium data of ternary system (water + butyric acid + Sesame oil) under atmospheric pressure at (308.15and 328.15) K were investigated.Type 1 behavior of LLE was observed in this ternary system. Also, at these two temperatures Experimental distribution coefficients and separation factors were calculated to evaluate the extracting ability of the solvent. The reliability and consistency of the tie line experimental data determined by applying Othmer−Tobias and Hand equations. The correlation of experimental data was obtained using NRTL model. The values of the parameters of NRTL model were determined by the root-mean-square deviation (rmsd) method.The amount of rmsd between experimental and calculated equilibrium mass fractions is about 1.63% .
