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

Abstract

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 V E, viscosity deviation Δ η and excess Gibbs free energy of activation Δ G E∗ of viscous flow have been calculated. The results were fitted by Redlich–Kister equation. All mixtures show negative values of V E due to increased interactions between unlike molecules or very large differences in the molar volumes of pure components at relatively low temperature.
