Ultrasonic, Volumetric and Viscometric Studies of 2-Hydroxy-5Chloroacetophenone in N, N-Dimethylformamide at Different Temperatures

Ultrasonic velocity, density and viscosity of 2-hydroxy-5-chloroacetophenone in N, N-dimethylformamide have been measured at varying temperatures. From these experimental data, various parameters like apparent with apparent molar volume (V_Φ) and apparent molar adiabatic compressibility (Ks,_Φ), were computed using density data with their limiting values and further acoustical parameters have been calculated. These parameters, were used to discuss interactions between the ketonic (>CO) group and DMF molecule. Viscosity data have been analyzed in the light of Jones-Dole equation and the constants A and B have been estimated. The results are interpreted to gain insight in to the changes in molecular association equilibria and structural effects in these systems.
