Ultrasonic velocity is measured experimentally at 3MHz frequency in the binary liquid mixture containing aniline and anisole at different temperatures over the entire composition range and theoretical values of ultrasonic velocity have been evaluated by using Nomoto’s relation, Impedance relation, Van Dael ideal mixture relation. These theoretical values are compared with the experimental values. A good agreement has been found between experimental and theoretical ultrasonic velocities.

Ultrasonic velocities calculated from various theories and relations like Nomoto's relation, Van dael ideal mixing relation, Impedance relation, Rao's specific velocity relation and Jungie's theory are compared with experimental values in binary liquid mixtures o-anisidine with o-cresol at temperatures 303.15, 308.15, 313.15 and 318.15 K over the entire mole fraction range. The relative applicability of these theories to the present system is checked and discussed. A good agreement is observed between experimental and theoretical values. The results are explained in the light of molecular interactions occuring in these mixtures.

The speeds of ultrasound in and densities of binary solutions of 1-butanol in hexane and cyclohexane were measured on the whole concentration range at 293.15 K. The experimental results in connection with literature data were used to calculate the isothermal compressibility coefficients and isochoric molar heat capacities for the pure components, as well as the excess molar volumes, excess adiabatic compressibilities, free volumes and the free intermolecular lengths for the binaries under test. The dependences of the excess properties on the mixture composition were compared and discussed in terms of the free intermolecular length and other factors affecting the solvation and self-association effects.

The speed of ulrtasound in and densities of binary solutions of ethanol, propan-2-ol and 2-methylopropan-2-ol in cyclohexane were measured on the whole concentration range at 293.15K. The excess molar volumes, free volumies, excess free volumes and adiabatic cmpressibility coeffcients, as well as the free intermolecular lenghts were determined for binaries. The dependance of the excess molar volumes and excess free volumes on the mixture composition were compared and discussed in terms of the intermolecular lenght and other factors afecting the self-association of alcohols and structural changes od the solvent.

The speed of ustrasound is and densities of ethanol + syclohexane mixtures were measured in the whole concentration range at 293.15K. The adiabatic compressibility coefficients and excess molar volumes, as well as the mean molecular radii, free intermolecular lenght and internal pressures were determined for the binaries. The dependance of the exess molar volumes and exess internal pressures on the mixture composition were compared and discussed in terms of the free intermolecular lenght and other factors affecting the self-association of the athanol and structural changes of the solvent.
