ABSTRACT
This paper presents the experimental data of densities and viscosities for aqueous 2-(methylamino)ethanol solutions at six temperatures in the range (298.15 to 343.15) K and refractive indices at seven temperatures in the range (293.15 to 323.15) K. Excess molar volumes, viscosity deviations, and molar refraction changes were calculated from the experimental results and correlated as a function of the mole fractions. The molar refraction changes were correlated as a function of the volume fractions. The partial molar volumes at infinite dilutions were determined from the apparent molar volumes. Negative values for both the excess molar volumes and the molar refraction changes were observed over the entire range of mole fractions, whereas the viscosity data exhibited positive deviations from linearity.
