Thermodynamic modelling of density and viscosity data of binary mixtures of haloarenes with cyclohexane

Abstract

ABSTRACT Densities (ρ) and dynamic viscosity () of the binary mixtures haloarenes (2-chlorotoluene (o-CT) or 4-chlorotoluene (p-CT) or 1,3-dichlorobenzene (m-DCB)) (1) + cyclohexane (2) were experimentally measured at T = (298.15–318.15) K and atmospheric pressure. The excess molar volume and deviation in dynamic viscosity were calculated using ρ and data. The values for o-CT or p-CT or m-DCB (1) + cyclohexane (2) are negative at all compositions. The is a temperature dependent property. The values decreases as temperature rise. The values were analysed using Prigogine-Flory-Patterson (PFP) theory too. The values are negative at all compositions. The viscosity increases with the rise in temperature because of the opening of interstitial voids in mixture. Singh equation and Bloomfield and Dewan (BFD) model were applied to predict and values. The viscosities of binary mixtures have been predicted using different correlations.
