Abstract : The study of interaction between solute-solute and solute-solvent interaction of substituted Quinoline pyrimidines in 70% (DMF+water) solvents by measuring ultrasonic velocity and density in different concentration of solute in the range (1x10-2M to 6x10- 4M) in 70% solvent has done. In the present investigation, different acoustical parameters, such as ultrasonic velocity (U), adiabatic compressibility (βs), partial molal volume (φv), apparent molal compressibility (φκ), solvation number (Sn) of substituted Quinoline pyrimidines in 70% DMF+water mixture at 300K have been studied. With the help of experimental data, the effect of concentration of solute on different acoustical parameters in DMF-water mixtures at a constant temperature and deviation of acoustical parameter from the ideality has been studied.

Keywords: Substituted Quinoline pyrimidines, ultrasonic velocity, Density, acoustic parameter.
