Excess molar volumes (VmE) and dynamic viscosities (η) have been measured as a function of composition for binary liquid mixtures of propylamine with 2,5-dioxahexane, 2,5,8-trioxanonane, 2,5,8,11-tetraoxadodecane, 3,6,9-trioxaundecane, and 5,8,11-trioxapentadecane at 298.15 K. The excess volumes are positive over the entire range of composition for the systems propylamine + 2,5-dioxahexane, and + 3,6,9-trioxaundecane, negative for the systems propylamine + 2,5,8,11-tetraoxadodecane, and + 5,8,11-trioxapentadecane, and change sign from positive to negative for the remaining system propylamine + 2,5,8-trioxanonane. From the experimental data, deviations in the viscosity (Δln η) and excess energies of activation for viscous flow (ΔG*E) have been derived. These values are positive for all mixtures with the exception of propylamine + 2,5-dioxahexane.Key words : excess volume, viscosity, binary mixtures.

The Ideal

A relation of excess volume and density is analyzed for binary liquid mixtures. It is shown that, unlike the ideal mixture, whose density is a monotonous function of composition, extremes may appear on the density curves of mixtures with non-zero excess volumes. Conditions for the existence of extremes are derived. Some examples are also given and briefly discussed.

Excess volume data for binary liquid mixtures of butylamine with aromatic and aliphatic hydrocarbons were measured as a function of composition dilatometrically at 303.15 and 313.15 K. The hydrocarbons include: benzene, toluene, three isomeric xylenes, hexane, heptane, and octane. The values of VE were found to be positive over the entire range of composition in all the eight systems at both the temperatures. The positive values were ascribed to the break-up of hydrogen bonds in the aggregates of amine by the hydrocarbons.
