溶液黏度的关联、预测模型和理论研究,在化学工程和溶液热力学理论中占有重要的地位。本文对基于Eyring反应速率理论的溶液黏度模型研究进行了概述。在基于Eyring黏度方程的基础上,分别介绍了通过溶液相平衡关系、基团贡献法和过量函数模型来计算混合物黏度的方法。最后对这3方面进行展望,提出了进一步发展基于Eyring理论黏度模型的研究建议。
The correlation of solution viscosity, prediction model and theoretical study occupy an important position in chemical engineering and solution thermodynamics. In this paper, the research on solution viscosity model based on Eyring reaction rate theory is summarized. Based on the Eyring viscosity equation, the methods to calculate the viscosity of the mixture through the solution phase equilibrium, the group contribution method and the excess function model are introduced respectively. Finally, the author makes a prospect of these three aspects and puts forward some suggestions to further develop the viscosity model based on Eyring’s theory.
