Densities, Viscosities of Pure 1-(2-Hydroxyethyl) Pyrrolidine, 3-Amino-1-Propanol, Water, and Their Mixtures at 293.15 to 363.15 K and Atmospheric Pressure

[Image: see text] Densities and viscosities of pure 1-(2-hydroxyethyl) pyrrolidine, 3-amino-1-propanol, water, and their blends’ data are reported from 293.15 to 363.15 K and at ambient pressure. Densities of pure water show higher values than that of 3-amino-1-propanol and 1-(2-hydroxyethyl) pyrrolidine, whereas pure 3A1P is more viscous than 1-(2-hydroxyethyl) pyrrolidine and water. The excess molar volumes and viscosity deviations from the data are correlated to the Redlich–Kister equation. The shape and value for the excess molar volumes and viscosity deviations could explain the intermolecular interaction between the molecules.
