Liquid-liquid equilibrium （LLE） data for the ternary system 2-methoxy-2-methylpropane （methyl tert-butyl ether） ＋ p-cresol ＋ water was measured at atmospheric pressure and temperatures of 298.15 K and 313.15 K. ...Liquid-liquid equilibrium （LLE） data for the ternary system 2-methoxy-2-methylpropane （methyl tert-butyl ether） ＋ p-cresol ＋ water was measured at atmospheric pressure and temperatures of 298.15 K and 313.15 K. From the distribution coefficients and selectivity, it was found that 2-methoxy-2-methylpropane is an efficient solvent to extract p-cresol from wastewater. The consistency of the experimental tie-line data was verified with the Hand and Bachman equations. These data were also correlated with the non-random two liquid （NRTL） and universal quasi-chemical correlation activity coefficient （UN1QUAC） models to yield binary interac- tion parameters for p-cresol extraction process evaluation. Both models agreed with experiments very well, yet the NRTL model showed even smaller average deviation than the UNIQUAC model.展开更多
