Viscosities of diethanolamine (DEA)-N-methyldiethanolamine (MDEA)-water ternary mixtures were measured by using a NDJ-1 rotational viscometer, with the temperature and mass concentration respectively ranging from 293.15~343.15 K and 30%~50%. The Grunberg-Nissan equation and Weiland equation were used to predict the viscosities of the binary and ternary aqueous solutions. The temperature and concentration dependence of the viscosity of aqueous solutions were demonstrated based on the experimental and theoretical results.

Key words: diethanolamine, N-methyldiethanolamine, aqueous solution, viscosity
