Excess thermo-acoustical parameters in binary liquid mixture containing n-butanol at different temperatures

Excess thermo acoustical parameters have been calculated from the experimentally measured data of ultrasonic velocity, viscosity and density in binary liquid mixtures containing n-butanol at different temperatures. These results are fitted to the Redlich–Kister polynomial equation. These results have been explained on the basis of the intermolecular interactions present in the liquid mixtures.
