butanol, 2-methyl-1-propanol, 2-butanol, and 2-methyl-2-propanol, including those of the
pure liquids, were measured over the complete composition range at 30° C. The
dependence of ρ, η, and n on composition was checked by using an empirical relation. The
experimental data were used to calculate excess molar volumes, VE, deviations in viscosity,
Δ η, excess free energies of activation of viscous flow, G* E, deviations in refractive index, Δ …
