ABSTRACT

Acoustic parameters study of newly synthesised substituted derivatives of benzothiazole were carried out in the present work. Parameter like Density and ultrasonic velocities of different concentrations from 0.01M to 0.000625 M of benzothiazolyl substituted derivatives with of 75%binary solvent mixture i.e. dioxane-water, acetone-water and DMSO-water mixtures were measured at 303.15 K (30oC) by using multifrequency ultrasonic interferometer at frequency 1 MHz and 3 MHz. The density, Concentration and ultrasonic velocity (U) were used to calculate adiabatic compressibility (?s), intermolecular free length (Lf), relative association (RA) and specific acoustic impedance (Z). The results have been interpreted in terms of solvent-solvent and solute-solvent interactions. Keywords: Relative association, ultrasonic velocity, Density, molecular interaction
