Densities and Dynamic Viscosities of Alicyclic Cyclohexane with Toluene, <i>o</i>-Xylene, and Mesitylene at <i>T</i> = (303.15 to 323.15) K and Atmospheric Pressure

Abstract

Densities and dynamic viscosities for organic binary mixtures of cyclohexane with toluene, o-xylene, and mesitylene were measured at T = (303.15 to 323.15) K and atmospheric pressure. The measurements were carried out over the entire range of composition using a bicapillary pycnometer and an A-type Ostwald viscometer. The excess molar volumes, thermal expansivities, and excess thermal expansivities were calculated from the experimental density data, while the viscosity deviations were obtained from the dynamic viscosity data. The excess results were correlated with the fourth-order Redlich–Kister-type polynomial equation. The excess properties of binary liquids were analyzed in terms of intermolecular interactions.
