Density (rho) and viscosity (eta) were determined over the whole concentration range for the binary mixtures of 1,2-diaminoethane + 1,2-ethanediol at (298.15, 303.15, and 308.15) K. The experimental results are compared with data published in the previous literature. The density values were used to calculate the excess molar volume (V(m)(E)). The calculated results are fitted to a Redlich-Kister equation to obtain the coefficients and estimate the standard deviations between the experimental and the calculated quantities. The values of V(m)(E) are negative over the entire composition range.
