Densities and Viscosities of Aqueous Ternary Mixtures of 2-(Methylamino)ethanol and 2-(Ethylamino)ethanol with Diethanolamine, Triethanolamine, <i>N</i>-Methyldiethanolamine, or 2-Amino-1-methyl-1-propanol from 298.15 to 323.15 K

Abstract

Densities and kinematic viscosities of aqueous ternary solutions of 2-(methylamino)ethanol and 2-(ethylamino)ethanol with diethanolamine, triethanolamine, N-methyldiethanolamine, or 2-amino-1-methyl-1-propanol were measured at temperatures from (298.15 to 323.15) K. The total amine concentration was held constant at 50 mass %, and the (MAE or EAE)/(DEA, TEA, MDEA, or AMP) mass % ratio was varied from 0/50 to 50/0, in 10 mass % steps. The experimental values were correlated with temperature and mole fraction.
