Densities and viscosities were measured under atmospheric pressure over the entire concentration range for the binary system 1,2-ethanediamine (EDA) + 1,4-butanediol (BDO) at T = 293.15, 298.15, 303.15, 308.15, 313.15, and 318.15 I< as a function of composition. Based on density and viscosity data, excess molar volumes (V-m(E)) and dynamic viscosity deviations (Delta nu) were calculated. V-m(E), and Delta nu values were correlated by a Redlich-Kister type function to obtain the coefficients and to estimate the standard deviation between the experimental and calculated quantities. Based on FTIR and UV-vis spectral results, the intermolecular interaction between EDA and BDO was discussed. (C) 2015 Elsevier B.V. All rights reserved.
