ABSTRACT

The isobaric vapor-liquid equilibria (VLE) at 101.32 kPa and densities, speeds of sound, and refractive indices at 298.15 K have been measured for binary liquid mixtures of 2-methoxy-2-methylpropane (MTBE) or 2-isopropoxypropane (DIPE) or 2-methoxy-2-methylbutane (TAME) and 1-propanol. The molar volumes, molar refractions, and isentropic compressibilities have been calculated from these experimental data. The excess molar volumes and the deviations in molar refraction and isentropic compressibility upon mixing have been satisfactorily correlated by the Redlich-Kister polynomial. The vapor-liquid equilibrium data have been found thermodynamically consistent and have been adequately correlated by means of Wilson, NRTL, and UNIQUAC equations. The ASOG and the original and modified UNIFAC group contribution methods have not afforded very adequate predictions of data involved in this study.
