Effect of temperature on excess molar volumes and viscosities of binary mixtures of ethylenediamine and water

Molar excess volumes ( V E) and viscosities have been evaluated for binary mixtures of ethylenediamine and water in the temperature range from 303.15 to 318.15 K at an interval of 5 K. Excess molar volumes V E have been computed from density while excess Gibbs free energy of activation Δ G ∗E is cal...

Zusammenfassung:	Molar excess volumes ( V E) and viscosities have been evaluated for binary mixtures of ethylenediamine and water in the temperature range from 303.15 to 318.15 K at an interval of 5 K. Excess molar volumes V E have been computed from density while excess Gibbs free energy of activation Δ G ∗E is calculated from viscosity deviation Δ η. The results were applied to Redlich–Kister equation. It is observed that all mixtures show negative values of V E obviously due to increased interactions between amino and hydroxyl groups of the components.
