ABSTRACT

This work reveals experimental liquid liquid equilibria (LLE) for ternary systems of (2-methoxyethanol + water + solvents) with methyl tert-butyl ether, ethyl acetate, and trichloromethane at 313.15 K and dichloromethane as solvent at 298.15 K under 101 kPa. The extraction capacity of the aforementioned solvents has been tested when it comes to the distribution ratio and separation factor according to the experimental data. The calculation results demonstrate that trichloromethane is an available solvent for extraction applications. Simultaneously, the reliability of the experimental LLE data was checked by Othmer Tobias and Hand correlations, and all of the linear correlation coefficients were greater than 0.98. The experimental LLE values were regressed to obtain binary interaction parameters with both NRTL and UNIQUAC activity coefficient models. Both models shows satisfactory agreement with all of the root-mean square deviation values below 0.50.
