ABSTRACT

Liquid-liquid equilibria (LLE) data of the quaternary system {Methyl Butyl Ketone + phenol + hydroquinone + water} and two relevent ternary system {Methyl Butyl Ketone + phenol + water} and {Methyl Butyl Ketone + hydroquinone + water} were measured at T = 313.2 K and p = 101.3 kPa. The experimental data were correlated with the nonrandom two-liquid (NRTL) and universal quasichemical (UNIQUAC) models. The root-mean-square deviation of the NRTL and UNIQUAC models were 0.144% and 0.0476%. Good agreement was found between experimental LLE data and those calculated from the NRTL or UNIQUAC equations for all studied systems in this work.
