We are carried out a systematic study of vapor-liquid equilibria and the fundamental excess properties for binary and ternary mixtures. In this work, three different thermodynamic properties(γ, hE, VE) were experimentally determined as a part of the thermo-physical study for the systems of MTBE and TAME with alcohols. These experimental properties were correlated with the gE models or Redlich-Kister polynomial. The activity coefficient at infinite dilution(γ∞) was calculated by second order extrapolation from the experimented activity coefficients and excess molar properties at infinite dilution (,) were calculated by correlated Redlich-Kister parameters. The extrapolated activity coefficient at infinite dilution were compared with the directly measured values by using differential ebulliometry. |
