Vapor−Liquid equilibria for the binary system hexane + 1,1-dimethylpropyl methyl ether at 298.15, 308.15, 318.15, and 328.15 K. Industrial & Engineering Chemistry Research, 41(5), 1364–1369.0888-5885https://hdl.handle.net/10016/44207Vapor-liquid equilibrium (VLE) data are reported for the binary mixtures formed by hexane and the branched ether 1,1-dimethylpropyl methyl ether (tert-amyl methyl ether or TAME). A Gibbs-van Ness type apparatus was used to obtain total vapor pressure measurements as a function of composition at 298.15, 308.15, 318.15, and 328.15 K. The system shows positive deviations from Raoult’s law. VLE data are analyzed together with excess enthalpy (Hm) and excess volume (Vm) data previously obtained at 298.15 K for these mixtures. The UNIQUAC model, the lattice-fluid model, and the Flory theory are used to simultaneously correlate VLE and Hm data and to correlate or predict Vm data. The original UNIFAC group contribution model and the modified UNIFAC (Dortmund model) are used to predict VLE data.6eng© 2002 American Chemical SocietyEnthalpyEthersMixturesVapor liquid equilibriumVapor pressureresearch articleBiología y Biomedicinaopen access136451369Industrial & Engineering Chemistry Research41
