摘　　要：根据正丁胺、正己胺、正癸胺、正十二胺等与叔丁胺、正己烷、环己烷、苯、乙酸甲酯、乙酸乙酯、乙酸丁酯、丙酮以及醇类物质所组成的二元溶液黏度试验数据,结合Eyring溶液黏度理论与UNIFAC基团贡献法,建立了一种用以计算含胺类物质混合溶液黏度的理论模型,并且利用文献黏度试验数据在该模型的框架上回归得到新的基团对的UNIFAC模型参数,并利用所建模型与回归得到的参数对混合溶液黏度进行计算,计算的绝对平均偏差为3.1%,可以满足实际工程应用的要求。Based on the viscosity test data of binary solutions composed of n-butylamine,n-hexamine,n-decamine,n-dodecylamine with tert butylamine,n-hexane,cyclohexane,benzene,methyl acetate,ethyl acetate,butyl acetate,acetone and alcohols,and in combination with Eyring’s absolute rate theory and UNIFAC group contribution method,a theoretical model for calculating the viscosity of mixed solutions containing amines is established.The UNIFAC model parameters of the new group pairs are regressed on the framework of the model by using the literature viscosity test data.The absolute average deviation of the viscosity calculation of the mixed solution by using the established model and the regressed parameters is 3.1%,which can meet the requirements of practical engineering application.
