The excess Gibbs free energies, enthalpies, entropies, and volumes are reported for mixtures of ethylene diamine-ethylene glycol at 25°C. The refractive indices of these liquid mixtures are also reported for 25°C.The excess thermodynamic properties have been reported for water-diethylamine solutions at 49.1°C, and ethyl alcoholdiethylamine solutions at 50°C. In both mixtures the excess enthalpies are large and negative over the entire composition range. The same is true for the TsE values. However, the Gibbs free energies are much smaller, and are also of opposite
