Abstract

Ultrasonic velocity (u), density () of binary systems Anisole with n- Hexane and n-Heptane have been measured for the entire composition range at 3 MHz at constant temperature 303 K. From the experimental data the acoustic parameters such as adiabatic compressibility (), intermolecular free length (Lf), acoustic impedance (Z), interaction parameter () and molar volume (Vm) have been computed and presented as functions of molar volume of Anisole. The deviations from ideal behavior is explained in terms of dipole-induced dipole inter molecular interactions between components of the mixtures.

Keywords: Anisole, n-Hexane, n-Heptane, acoustic compressibility, acoustic impedance
