Densities and viscosities at six temperatures in the range (298.15 to 343.15) K and refractive indices at five temperatures in the range (298.15 to 333.15) K are reported for the aqueous 2-((2-aminoethyl)amino) ethanol solutions. Excess molar volumes, viscosity deviations, and molar refraction changes are calculated from the measurement results and correlated as a function of the mole fractions. Partial molar volumes at infinite dilutions are determined from apparent molar volumes. Negative values for both excess molar volumes and molar refraction changes are observed over the entire range of mole fractions, whereas viscosity data exhibit both negative and positive deviations.
