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.

Excess volumes for binary mixtures of 1-chlorobutane with hexane, heptane, octane and nonane were measured dilatometrically at 303.15 K. Excess volumes are positive over the entire range of composition in the four mixtures. Further, it is observed that increase in chain length increases the magnitude of the excess function.

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 volumes for the binary liquid mixtures of methylisobutylketone with benzene, toluene, chlorobenzene, bromobenzene, and nitrobenzene have been measured at 303.15 and 313.15 K. Excess volumes were negative for all the systems over the entire range of composition and at both the temperatures. The behaviour of VE as a function of composition and temperature was studied. Viscosity data have also been determined for the five systems at 303.15 K. The excess viscosity, Δ ln η, has been calculated and its behaviour as a function of composition was investigated. The results of VE and Δ ln η have been discussed in terms of dipole – induced dipole and dipole–dipole interactions between the components. VE and Δ ln η were analysed in the light of Prigogine–Patterson–Flory equation of state theory and Bloomfield and Dewan's viscosity relations.

Excess volumes of binary mixtures of cyclohexane with phenol, o-ohlorophenol, p-chlorophenol, o-cresol, m-cresol, and p-oresol have been measured. The results have been used as an indication of relative strengths of intermolecular hydrogen bonds in phenol and substituted phenols. Viscosities of phenol, o-cresol, and o-chlorophenol in admixtures with cyclohexane have also been measured and the results of viscosity data were examined in the light of the relations developed for binary mixtures.

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.
