Abstract
The effect of magnetic field on the liquid-liquid equilibrium of two ternary systems (water + acetic acid + butyl acetate and water + acetic acid + dimethyl succinate) at 298.15 K under atmospheric pressure was investigated. The results obtained show that the strength of the magnetic field (0.02 T) affects the solubility of acetic acid in the used organic solvents. Distribution coefficients and separation factors were determined from the experimental LLE tie-line data for these systems. The comparisons indicated that the separation factor for the mixtures with dimethyl succinate is more effective than those with butyl acetate. The reliability of the tie-line data was ascertained through the Othmer-Tobias method. The tie-line data of studied ternary systems were also correlated using NRTL method and the values of the binary interaction parameters were obtained. It was concluded that the NRTL model accurately correlates the experimental data of the mentioned ternary systems.
