الملخص العربي
Some physical properties (e.g., density, viscosity and refractive index) of quaternary liquid mixture (2,5-hexandione + cyclopentanol +
cyclohexanol + 3-heptanol) of different mole fraction of the components have been measured at 298.15 K. From the experimental density,
viscosity and refractive index the values of excess volume (VE), deviation of viscosity (Δη), deviation of refractive index (Δn) and excess
free Gibbs energy of activation of flow (ΔGE) have been calculated. the nature of molecular interactions between the components of
liquids mixtures has been explained due to interaction parameters and excess properties. The FTIR spectrum shows a drastic change in the
frequency and intensity after mixing of organic compounds at all entire range of mole fraction under study. The shift in the frequency
values might be due to H-bonding or dipole-induced dipole interaction.
