Density (rho) and viscosity (eta) data for the binary system of polyethylene glycol 400 (PEG) + 1.2-ethanediamine (EDA) over the whole concentration range as a function of composition were measured at T = (293.15, 298.15, 303.15, 308.15, 313.15, and 318.15) K under atmospheric pressure. Based on experimental density and viscosity data, the excess properties of the PEG (1) + EDA (2) mixtures, including excess molar volume (4) and viscosity deviation (Delta eta), excess free energies of activation (Delta G*(E)), apparent molar volume (V-phi.1 and V-phi.2), and partial molar volumes ((V) over bar (1) and (V) over bar (2)), were calculated respectively. Meanwhile, the results of V-m(E), Delta eta and Delta G*(E) were fitted by a Redlich-Kister equation to obtain coefficients and to evaluate the standard deviations (sigma) between the experimental and calculated quantities. Additionally, based on FTIR and UV-Vis spectral results of PEG (1) + EDA (2) mixtures with various concentrations, intermolecular interaction of PEG with EDA was discussed.
