Study of Ultrasonic Parameters of Aqueous Solutions of Phloroglucinol

Phloroglucinol ( 1,3,5-Trihydroxy benzene ) is used in the preparation of pharmaceuticals, dyes and resins. It is also used in the preparation of cut flowers, textile dyeing and printing and in analytical chemistry. Ultrasonic parameters provide valuable information about various inter and intra molecular interactions in solutions. Ultrasonic velocity, density and viscosity of aqueous solutions of Phloroglucinol at various concentrations and at various temperatures ranging from 303 K to 323 K have been experimentally determined. Ultrasonic parameters such as Acoustical impedance, Adiabatic compressibility, Intermolecular free length, Rao’s constant, Wada’s constant, Acoustical relaxation time, Relative association, Available volume and Vander Waal’s constant of these solutions are computed on the basis of these measurements. Various molecular interactions in these solutions have been analyzed on the basis of the variations of these parameters with concentration and temperature.
