Abstract
Density (ρ), ultrasonic velocity (u) of DMF-Water and components1-Benzothiazol-2-yl-3-(2-hydroxy-5-methyl phenyl)-5-(4-methoxy phenyl) pyrazoline (BHMPMPP), 1-Benzothiazol-2-yl-3-(2-hydroxy-5-methyl phenyl)-5- phenyl pyrazoline (BHMPPP) and 1-Benzothiazol-2-yl-3-(2-hydroxy-5-methyl phenyl)-5-(4-chloro phenyl) pyrazoline (BHMPCPP) in different concentrations of DMF-Water mixture have been determined at 303.15K temperature at 2MHz and 4MHz frequency range. Acoustical parameters such as Adiabatic Compressibility (β), Intermolecular free length (Lf), Acoustic Impedance (Z), Relative Association (RA), Isothermal Compressibility (βT), Thermal Expansion Coefficient (α), Interaction Parameters (χ), solvation number (Sn) and some other parameters have also been investigated from density and ultrasonic velocity of experimental data. The results are discussed on the basis of molecular interactions viz. solute-solute, solute-solvent interaction.
