Abstract
Abstract Density, ultrasonic velocity of binary mixture of 2-amino-5-nitrothiazole + N,N-dimethylformamide (NNDMF), 2-amino-5-nitrothiazole + acetonitrile, and 2-amino-5-nitrothiazole + ethanol were measured at different concentrations of 2-amino-5-nitrothiazole and at different temperatures (303.15, 308.15, 313.15, 318.15 and 323.15) K. Acoustical parameters such as adiabatic compressibility, intermolecular free length, acoustical impedance, sound velocity number, and relative association were determined from experimental data of density and ultrasonic velocity. The effect of temperature and concentration variations in the strength of molecular interaction has been studied. Effective correlation was observed in terms of solute–solvent and solvent–solvent interaction at all temperatures and concentration.
