Abstract
ABSTRACT Excess molar volume, excess isentropic compressibility, deviation in viscosity and excess Gibbs free energy for activation of viscous flow for binary mixtures of allyl alcohol (C) with benzyl aldehyde (C1), benzylamine (C2) and benzyl alcohol (C3) components in selected compositions were determined from the measured values of densities (ρ), viscosities (η) and speeds of sound (u) of pure components and their mixtures at 303.15–313.15 K. These results were analysed by different theoretical models, such as PFP and Jouyban–Acree model. The effect of various functional groups on the excess properties was discussed in terms of disruption of H-bonding and dipole–dipole interaction between the components of the mixtures. The thermodynamic results of the present investigation have been correlated with FTIR spectral studies and have obtained a good agreement.
