Abstract: Ultrasonic velocity and density values have been measured at 303 K in binary mixtures containing aniline, toluene and n-butanol; and the thermodynamical approach is applied to evaluate the mixtures' molar volume, adiabatic compressibility, intermolecular free length and excess values. The observed results are interpreted in terms of molecular interaction between the components of the mixtures. Observed excess values and their fittings of R-K type equations lend further support to the observation made in the binary system.
Keywords: Binary, velocity, density, molecular interactions, R-K type equations
