Abstract :

The ultrasonic velocity(υ), density (ρ) and viscosity (η) of ternary liquid mixtures contain three aromatic amine compounds such as aniline, N-methyl aniline, N,N-dimethylaniline with cinnamaldehyde in n-hexane at 303K a wide range concentration (1x10-4M to 1x10-3M). From the experimental data of various acoustical parameters such as adiabatic compressibility (κ), free length(Lf ), internal pressure (πi), cohesive energy (CE), formation constant (K) have been computed using standard relation. The excess values of these parameters are also evaluated for aldehyde and amine in polar medium like n-hexane have been investigated by ultrasonic measured. The result is interpreted in terms of molecular interaction such as dipole – dipole interaction through hydrogen bonding between components of mixtures. These values indicate complex formation and ion-solvent interaction between aromatic amine compounds and cinnamaldehyde in n-hexane medium.
