Viscosities, excess molar volume of binary mixtures of ethanolamine with water at 303.15, 308.15, 313.15 and 318.15 K

The density and viscosity values of binary mixtures of ethanolamine with water were measured at 303.15, 308.15, 313.15 and 318.15 K, using this data excess molar volume VE, viscosity deviation Δη and excess Gibbs free energy of activation ΔGE∗ of viscous flow have been calculated. The results were fitted by Redlich–Kister equation. All mixtures show negative values of VE due to increased interactions between unlike molecules or very large differences in the molar volumes of pure components at relatively low temperature.
