Surface-Tension of Binary-Mixtures of Water Plus Monoethanolamine and Water Plus 2-Amino-2-Methyl-1-Propanol and Tertiary Mixtures of These Amines with Water from 25-Degrees-C to 50 Degrees-C
The surface tension of aqueous solutions of monoethanolamine, 2-amino-2-methyl-1-propanol, and monoethanolamine + 2-amino-2-methyl-1-propanol was measured at temperatures from 25 degrees C to 50 degrees C. The concentration ranges were 0-100 mass % monoethanolamine and 2-amino-2-methyl-1-propanol, and for tertiary mixtures 50 mass % total amine concentration (the concentration range for each amine was 0-50 mass %). The experimental values were correlated with temperature and mole fraction. The maximum deviation was in both cases always less than 0.5%.
