Study of Molecular Interactions among Esters, Toluene and Aniline using Ultrasonic Technique
Abstract
Abstract
The interactions of esters (ethyl acrylate and ethyl benzoate) with common binary of toluene + aniline were studied using ultrasonic velocity, density and viscosity measurements at 303, 308 and 313K. From the experimental data, the acoustical parameters such as adiabatic compressibility (β), free length (Lf), free volume (Vf), internal pressure (πi), acoustic impedance (Z) and their excess values were estimated using standard relation. The results of these parameters are attributed to weak hydrogen bond between solute and solvent molecules.
