ABSTRACT

The vapour pressures of liquid (2-diethylaminoethylamine (2-DEEA) + cyclohexane) mixtures were measured by a static method between (T = 273.15 and T = 363.15) K at 10 K intervals. The excess molar enthalpies at 303.15 K were also measured. The molar excess Gibbs energies were obtained with Barker's method and fitted to the Redlich-Kister equation. The Wilson equation was also used. Deviations between experimental and predicted excess molar Gibbs energy and excess molar enthalpy, by using DISQUAC model, were evaluated. The proximity effect of N atoms produces a decrease of the interactional parameters.
