Abstract

New measured data for density, (ρ), dynamic and kinematic viscosities, (μD and μc), and refractive index, (nD), are presented at T = 298.15 K and p = 0.1 MPa for binary and ternary mixtures containing dibutyl ether, 2-butanol, and cyclohexane. As a result, the derived properties are estimated based on the measured data. Excess molar volume, (VE), dynamic viscosity deviation (ΔμD), and deviation in refractive index, (ΔnD), as derived properties, are fitted using the Redlich–Kister equation. In addition, perturbed-chain statistical associating fluid theory equation of state is employed to correlate the measured data of density.
