چکیده انگلیسی
The vapour pressures of liquid (3-diethylaminopropylamine (3-DEPA) + n-heptane) mixtures were measured by a static method between T = (303.15 and 343.15) K at 10 K intervals. The molar excess enthalpies HE at T = 303.15 K were measured for the systems {3-DEPA + CnH2n+2 (n = 6, 7, 12)}. The molar excess Gibbs free energies GE were obtained with Barker’s method and fitted to the Redlich–Kister equation. The Wilson equation was also used. Deviations between experimental and predicted GE and HE, by using group contribution UNIFAC (Gmehling version) model, were evaluated.
