Abstract
In this paper, experimental measurements of densities and viscosities of Ethanol + Diethylenetriamine (DETA) or Aminoethylethanolamine (AEEA) binary liquid mixtures are reported at temperatures of 298.15, 303.15 and 308.15K and atmospheric pressure over the whole composition range. From the experimental data, excess molar volume, excess coefficient of thermal expansion, excess partial molar volume, isothermal coefficient of excess molar enthalpy, excess Gibbs free energy of activation and excess viscosity were calculated. The sign and magnitude of excess quantities were used to discuss about the nature and strength of molecular interactions in these solutions. The obtained excess molar volumes were correlated with Redlich-Kister polynomial equation. Moreover, the measured values of densities were predicted with Peng-Robinson and PC-SAFT equation of states and the experimental values of viscosities were correlated and predicted by different semi-empirical equations.
