Abstract
A novel technique has been developed for the determination of Kirkwood–Buff integrals by employing ultrasonic velocity and density only. To the best of our knowledge, there exists no method for the computation of Kirkwood–Buff integrals from ultrasonic velocity and density only for multicomponent liquid mixtures. In this context, K–B integrals have been determined for three ternary mixtures, namely, benzene + cyclohexane + chlorobenzene, benzene +cyclohexane + toluene and toluene + cyclohexane + carbontetrachloride under one atmospheric pressure and 298.15 K by employing a statistical mechanical theory propagated by Arakawa and O. Kiyohara, [Arakawa and O. Kiyohara, Bull. Chem. Soc. Jpn. 43, 975 (1970)].
