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.

Benzene Toluene

The excess volumes of twenty binary mixtures of four aromatic hydrocarbons (benzene, toluene, ethylbenzene, and p-xylene) and five linear alkanols (methanol, ethanol, 1-propanol, 1-butanol, and 1-pentanol) at 20 °C are reported. The excess volume of systems with the same alkanol increases with increasing size and number of substituents on the benzene ring. For systems with the same aromatic hydrocarbon it increases with the length of the alkanols. The dependence of ∆V/φ1ϑ2 values on composition is noticeably asymmetric. Systems with benzene as one of the component show larger ∆V/φ1ϑ2 values than other systems and systems with methanol show different compositional dependence patterns.

Densities of binary mixtures of 1,1,2-trichlorotrifluoroethane + dibromomethane, + bromochloromethane, or + bromotrichloromethane were measured over their entire composition ranges at 288.15 and 308.15 K. Thermal expansion coefficients (α) and excess molar volumes (VEm) were calculated. Moreover, densities at 298.15 K and pressures up to 80 bar (1 bar = 100 kPa) were determined for these same mixtures. Isothermal compressibilities (KT) of the pure liquids and their mixtures were obtained.Key words: density, excess volume, thermal expansion coefficient, isothermal compressibility.
