Specific Molecular Interactions of Dihydropyridine Moiety in Polar and Non-Polar Solvents at Various Concentrations and Temperatures 303-318 K on Ultrasonic Data.

Abstract: Ultrasonic studies of compounds of dihydropyridine series in polar and non-polar solvents at various concentrations and temperatures 303-318 K. Density and ultrasonic velocity and different thermo-acoustical parameters measured. Rao's constant, molar volume, Wada's constant, isothermal compressibility reported with the help of these data using standard formulae. Ethanol and DMF selected as polar and non-polar solvents respectively. The variation in thermoacoustical parameters with temperature and concentration shows that the solute-solute molecular interaction takes place in solution which is more in DMF. [ABSTRACT FROM AUTHOR]
