摘要

本文基于Eyring纯液体粘度理论

并引进局部克分子组成概念

提出一个液体混合物粘度方程其中 A_(ij)=exp〔-(g_(ij)-g_(ii))/RT〕该方程被应用于近30个二元体系和5个三元体系的计算

结果表明

它对于二元实测粘度数据的关联和多元粘度～组成关系的预测都是相当有效的。文中对方程的建立、参数的物理意义和方程的适用性进行了探讨。

Abstract

Based on Eyrings theory of viscosity of pure liquids

an equation for the calculation of the viscosity of liquid mixtures was proposed from the concept of local molar composition: where V represents the viscosity

V molar volume

ga interaction energy between the molecules of the same kind

ga interaction energy between the molecules of the defferent kinds

x have their conventional meaning

and the subscripts i

j denote -component and j-component respectively. By the use of this equation

thirty binary systems and five ternary systems were tested with satisfactory agreement between calculated and experimental values. This equation is

therefore

valid both for correlate viscosities of binary systems and predict those of multicomponent systems from binary parameters.
