Prediction of the Viscosity of Liquid Mixtures: An Improved Approach1

A recently developed theoretically based scheme for the prediction of the viscosity of gas mixtures is modified by making use of the hard-sphere theory and applied to the prediction of the viscosity of liquid mixtures. Preliminary results are compared with viscosity measurements of mixtures of n-hexane with toluene and with cyclohexane, and demonstrate the predictive power of this scheme.
