摘要：
This paper presents binary vapor-liquid equilibria (VLE) for the ether-aromatic systems including 2-methoxy-2-methylbutane (TAME) and 2-methoxy-2-methylpropane (MTBE) with toluene. The data sets were measured using a dynamic experimental method over a temperature range from (308 to 323) K. The isothermal data were correlated using several liquid-phase excess Gibbs energy models including NRTL, UNIQUAC, and the Wilson model, with the respective model parameters fitted using the Marquardt optimization algorithm. Infinite dilution activity coefficients in the oxygenate-depleted region are reported. The isothermal VLE data are shown to be thermodynamically consistent.
