ABSTRACT

The vapor pressures of liquid [2-diethylaminoethylamine (2-DEEA) + n-heptane] mixtures were measured by a static method between T = (273.15 and 363.15) K at 10 K intervals. The excess molar enthalpies HE at 303.15 K were also measured. The molar excess Gibbs energies GE were obtained with Barker s method and fitted to the Redlich Kister equation. The Wilson equation was also used. The molar excess Gibbs energies and the molar excess enthalpies were used to test the applicability of group-contribution models, including the modified UNIFAC model in the versions of Larsen and Gmehling and the Disquac model. Particularly, the proximity effect of N atoms was analyzed.
