Online published on 26 March, 2018. Abstract The present work describes the synthesis, characterization, thermal analysis and thermo-acoustical parameters of 5-(3-methoxyphenyl)-1-phenyl-2-((m-tolylamino)methyl)-1H-1, 2, 4-triazole-3(2H)-thione(MM4a). The thermal behavior of MM4a was studied by thermal techniques and associated kinetic parameters were evaluated according to Freeman-Carroll method. The density (ρ), viscosity (η) and ultrasonic sound velocity(U) of 1, 4-Dioxane and solutions of MM4a (0.1-0.01 M)were investigated at three different temperature (303, 308 and 313) K and atmospheric pressure. Some acoustical parameters such asadiabatic compressibility (κs), intermolecular free path length (Lf), Rao's molar sound function (Rm), Van der Waals constant (b), internal pressure (π), free volume (Vf) and solvation number (Sn), entropy of activation (ΔS#), pre-exponential factor (A), enthalpy of activation (ΔH#) and Gibbs free energy of the decomposition (ΔG#) were calculated. The results obtained were interpreted in terms of solute-solvent and solute-solute interactions.
