Excess volumes of binary mixtures of alcohols in methylcyclohexane have been determined at 30.0 and 40.0 °C, using a modified dilatometer of Brown and Smith. The systems include: (I) 1-propanol – methylcyclohexane, (2) 1-butanol – methylcyclohexane, (3) 1-pentanol–methylcyclohexane, and (4) 1-hexanol–methylcyclohexane. The VE values are found to be positive over the entire range of composition in all the four systems and the values are interpreted on the basis of the structure-breaking effect of methylcyclohexane.

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.

Isentropic compressibilities of binary mixtures of butylamine + hexane, butylamine + heptane, and butylamine + octane were determined at 303.15 and 313.15 K. The three mixtures exhibit positive deviations in compressibility. This is ascribed to a structure-breaking effect of n-alkanes. The deviation becomes more positive with increase in chain length of n-alkanes and with increase in temperature.

Excess volume data for mixtures of 1-propanol, 1-butanol, 1-pentanol, and 1-hexanol with methylethylketone were determined at 303.15 and 313.15 K. These volumes are negative with 1-propanol and increasingly positive with the higher homologs, suggesting that the structure-making effect of the ketone outweighs the structure-breaking effect in the first mixture of the series while the structure-breaking effect dominates in the other three mixtures. Further, the temperature coefficient of VE was found to be positive in all four mixtures.

Excess Volumes

Excess volumes of mixtures of 1-propanol +, 1-butanol +, 1-pentanol +, and 1-hexanol + diethylketone have been measured at 303.15 and 313.15 K. Of the four mixtures included here 1-propanol + diethylketone shows an inversion in sign in VE at 313.15 K. VE becomes more positive with increase in temperature.

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.
