Densities, viscosities and excess properties for n-nonane with alcohols (C3-C6) from 303.15 K to 333.15 K at atmospheric pressure

Abstract

The volumetric and viscometric properties of the liquid mixtures are of importance for industrial application and theoretical calculation. This work reports the density and viscosity of the binary mixtures of n-nonane with 1-propanol, 1-butanol, 1-pentanol, and 1-hexanol from 303.15 K to 333.15 K at atmospheric pressure in the whole composition ranges. Excess properties such as excess molar volumes and viscosity deviations were calculated and correlated as the type of Redlich-Kister equation. In addition, the densities and viscosities for the studied mixtures were correlated using PC-SAFT equation and McAllister four-body viscosity model. For n-nonane with 1-propanol, 1-butanol, 1-pentanol, and 1-hexanol mixtures, the average absolute relative deviations between the experimental density data and calculate values from PC-SAFT equation are 0.39%, 0.46%, 0.31%, and 0.38%, respectively. And the average absolute relative deviations of viscosity from McAllister four-body model are 0.82%, 0.86%, 1.32%, and 1.01%, respectively.
