Additives of Shear Viscosities of C10 Hydrocarbon Mixtures.

Abstract

Shear viscosities and densities have been measured from 50 Cto as low as -56 C for n-decane, n-butyl cyclomexane, cis-decalin, 2,7-dimethyloctane, n-butyl benzene, and their mixtures. A simple semi-empirical equation based on the assumption of additivity of free volumes was applied to mixtures of the first three of these and gives quite good predictions of the combined temperature-composition dependence of the viscosity of these systems. A substantial fraction of the viscosity differences among these three liquids can be accounted for simply on the basis of differences in the sizes of the molecules. (Author)
