Abstract

The present work describes the synthesis, thermo-acoustical parameters and thermal analysis of 5-(3-methoxyphenyl)-1-phenyl-2-((m-tolylamino)methyl)-1H-1,2,4-triazole-3(2H)-thione (T4a). The viscosity (η), density (ρ) and ultrasonic sound velocity (U) of N,N-dimethyl formamide (DMF) and solutions of T4a (0.1-0.01 M) were investigated at three different temperature (303, 308 and 313) K and atmospheric pressure. Some acoustical parameters such as intermolecular free path length (L_f), adiabatic compressibility (κ_s), Rao’s molar sound function (R_m), internal pressure (π), Van der Waals constant (b), free volume (V_f) and Gibbs free energy of the decomposition (DG^#), solvation number (S_n), enthalpy of activation (DH^#), pre-exponential factor (A) and entropy of activation (DS^#) were calculated. The results obtained were interpreted in terms of solute-solvent and solute-solute interactions.
