Description :
Density, ultrasonic velocity of pure solvent N,N-dimethylformamide (NNDMF) and ligand solutions of substituted thiazoles in 70% NNDMF-water mixture were measured at different temperatures (303.15, 308.15, 313.15 and 318.15)K. Acoustical parameters such as adiabatic compressibility, intermolecular free length, acoustical impedance, apparent molar volume and relative association were determined from experimental data of density and ultrasonic velocity. The effect of temperature variations on the strength of molecular interaction has been studied. An excellent correlation represents in terms of solute-solvent and solvent-solvent interactions at all temperatures.
Keywords: density, ultrasonic velocity, acoustical parameter, molecular interaction, thiazole, NNDMF.
