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.
The content of diethanolamine (DEA) -N-methyldiethanolamine (DEA) in the temperature range of 293.15 ~ 343.15 K was determined with NDJ-1 rotary viscometer and the mass fraction of alcohol amine was in the range of 30% ~ 50% MDEA) .The viscosity of DEA aqueous solution, MDEA aqueous solution and MDEA-DEA aqueous solution were predicted by Grunberg-Nissan equation and Weiland equation.On the basis of experimental and theoretical prediction, the viscosity and temperature of aqueous solution of alkanolamine And the concentration of alcohol amine relationship.
