ABSTRACT
Experimental liquid-liquid equilibria (LLE) data for ternary (methyl propyl ketone + hydroquinone + water) and (methyl propyl ketone + resorcinol + water) systems were determined under atmospheric pressure at T = (298.15, 318.15 and 333.15) K. Distribution coefficients and separation factors were calculated to evaluate extraction effectiveness. Hand, Bachman, and Othmer-Tobias equations were utilized to confirm consistency of experimental LLE data. Thermodynamic NRTL and UNIQUAC models were used to correlate experimental LLE data, and corresponding binary interaction parameters were obtained. The estimated data from two models agree well with experimental LLE data. NRTL model gives a better agreement than UNIQUAC model for ternary (methyl propyl ketone + hydroquinone or resorcinol + water) systems.
