Studies of Some Acoustical Properties of 1-(2-Hydroxy-5-Methyl Phenyl)-3-(4'-Methoxy Phenyl)-1,3-Propanedione in 70% Acetone-Water Mixture at 30oC

Abstract

Ultrasonic velocities and densities of different concentrations of
1-(2-hydroxy-5-methyl phenyl)-3-(4' -methoxy phenyl)-1,3-propanedione
in binary mixture (70% acetone-water) have been
evaluated at 30^oC by using single crystal interferometer at a frequency
of 1 MHz. The ultrasonic velocity, density and concentration
were used to calculate apparent molal volume (φ_v), adiabatic compressibility
(β_s), apparent molal compressibility (φ_k(s)), intermolecular
free length (L_f), specific acoustic impedance (z) and
relative association (R_A) through the light on the solute-solvent and
solute-solute interactions.
