Languages of publication
The estimation of density, viscosity and ultrasonic velocity of solution of pyrimidine derivatives in 1,4-dioxane and N,N-dimethylformamide was carried out as functions of concentration (0.01 to 0.1 M) and temperature (298.15 to 318.15 K). Some acoustical and apparent parameters such as acoustical impedance (Z), intermolecular free length (Lf), adiabatic compressibility (κs), molar compressibility (W), Vander Waals constant (b), relaxation strength (r), internal pressure (π), apparent molar compressibility (fk), apparent molar volume (fv) etc., have been evaluated using experimental data of ultrasonic velocity (U), density (ρ) and viscosity (η). The characterization of these synthesized compounds was done by IR, 1H NMR and mass spectral data.
