Densities and viscosities were measured for monoethanolamine (MEA) + water, MEA + ethanol, and MEA + 2-propanol at 303.15, 313.15, and 323.15 K. The excess volumes and viscosity deviations from the mole fraction average were calculated and correlated by a Redlich-Kister type equation. McAllister’s models were also applied to correlate the kinematic viscosities.
