ABSTRACT

The surface tension of aqueous solutions of MAE (2-(methylamino)ethanol) and EAE (2-(ethylamino)ethanol) were determined at (293.15 to 323.15) K over the entire range of concentrations of binary mixtures with water. Also, ternary mixtures of previous systems with two amines commonly employed in carbon dioxide capture processes (TEA, triethanolamine, and MDEA, N-methyldiethanolamine) were studied. Equations were used to fit the experimental data at different compositions and temperatures.
