Acoustical Studies on Binary Mixtures of Methyl Acrylate with Benzene and Mono-Substituted Benzenes at 313.15 K

Abstract

Ultrasonic velocities and Densities of binary mixtures of Methyl Acrylate (MA) with Benzene and mono-substituted Benzenes like Benzene (B), Methyl benzene (MB), and Ethyl benzene (EB) have been measured at 313.15 K, by using these data, various acoustical parameters like Isentropic compressibility (KS), Intermolecular free length (Lf), acoustic impedance (Z) and relative association (RA) were calculated, further by using these acoustical parameters, excess properties like excess ultrasonic velocities (uE), excess acoustic impedance (ZE), excess isentropic compressibility (KSE) and excess inter-molecular free-length (LfE) were calculated and fitted to Redlich-Kister equation. The existence of inter-molecular interactions between the components in the liquid mixtures was discussed.
