ABSTRACT
Densities, ?, and viscosities, ?, of aqueous solutions of N-(2-hydroxyethyl)morpholine were measured over the entire composition range at T = (293.15, 303.15, 313.15, 323.15, 333.15) K and at atmospheric pressure. The excess molar volumes VE and viscosity deviations ?E of aqueous solutions were calculated from the experimental results of density and viscosity measurements and fitted to the Redlich Kister polynomial equation. Apparent molar volumes V, partial molar volume at infinite dilution V8, and the thermal expansion coefficient were also calculated. The VE values were found to be negative over the entire composition range at all temperatures studied and become less negative with increasing temperature, whereas the viscosity data ?E exhibited positive deviations from ideal behaviour.
