studies of intermolecular interactions through thermoacoustic measurements for the binary liquid mixtures containing ortho methoxy aniline and n-methyl aniline in benzene at 303-318 k and ambient pressure

In this communication, we have measured the densities and ultrasonic velocities for the binary mixtures of (ortho methoxy aniline + benzene) and (n-methyl aniline + benzene) over the entire volume fraction range 0.1-1 at303k- 318k and at ambient pressure. the experimentally obtained data were used to evaluate different derived parameters such as adiabatic compressibility, intermolecular free length, acoustic impedance, molar volume, molar sound velocity, molar compressibility, relative association, excess volume, and excess adiabatic compressibility. the outcome of all derived parameters is well explained by intermolecular interaction studies present in the non-aqueous binary organic liquid mixture. moreover, the densities and ultrasonic velocities of the binary mixtures were used to compare different correlating relations. the negative values of the excess volume and excess adiabatic compressibility with volume fraction and temperature confirm the presence of strong interaction through dipole-dipole and dipole-induced dipole interactions in the studied systems.
