The synthesis of some derivatives of dihydro pyrimidines and characterization was done by IR, 1H NMR, and mass spectral data. Ultrasonic velocities and density of various solutions of different concentrations of these synthesized compounds in dimethyl formamide and dimethyl sulfoxide have been measured at 298.15 K. Using these experimental data, some acoustical parameters are calculated which are interpreted in terms of solute-solute and solute-solvent interactions in different solutions.
