用NDJ-1型旋转粘度计测定了293.15～343.15 K温度范围内、醇胺质量分数介于30%～50%时, 二乙醇胺(Diethanolamine, DEA)-N-甲基二乙醇胺(N-methyldiethanolamine, MDEA)水溶液的粘度. 以Grunberg-Nissan方程和Weiland方程对DEA水溶液、MDEA水溶液和MDEA-DEA水溶液的粘度进行了预测. 在实验测定和理论预测的基础上, 阐明了醇胺水溶液的粘度与温度和醇胺浓度之间的关系.

关键词: 二乙醇胺, N-甲基二乙醇胺, 水溶液, 粘度

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
