Surface Tension of Aqueous Binary Mixtures of 1-Amino-2-Propanol and 3-Amino-1-Propanol, and Aqueous Ternary Mixtures of These Amines with Diethanolamine, Triethanolamine, and 2-Amino-2-methyl-1-propanol from (298.15 to 323.15) K

The surface tension of aqueous binary solutions of 1-amino-2-propanol and 3-amino-1-propanol and aqueous ternary solutions of these amines with diethanolamine, triethanolamine, and 2-amino-2-methyl-1-propanol was measured at temperatures from 298.15 K to 323.15 K. For binary mixtures, the concentration range was 0−100 mass percent alkanolamine, and for ternary mixtures, the concentration range for each amine was 0−50 mass percent. The experimental values for binary mixtures were correlated with mole fraction by an empirical equation (the maximum deviation was in both cases always less than 0.2%).
