ABSTRACT

This paper presents experimental data on the density of aqueous blends of (2-(methylamino)-ethanol (MAE) + 2-amino-2-methyl-1-propanol (AMP)) and (2-(methylamino)-ethanol (MAE) + N-methyl-diethanolamine (MDEA)) at (298.15, 303.15, 308.15, 313.15, 318.15, and 323.15) K. This study also presents surface tension data of the aforesaid aqueous amine blends over the temperature range (298 to 323) K. The total amine mass fraction in all solutions was kept within 30 % in view of recent interest in using concentrated amine solutions in gas treating. Density and surface tension data of the ternary mixtures are presented as a function of temperature and amine composition.
