Studies on Thermodynamic Properties of Some Imidazolinone Derivatives in DMF at 308.15 K

Density, ultrasonic velocity and viscosity of imidazolinone derivatives are studied in dimethyl formamide (DMF) at 308.15 K. From the experimental data, various acoustical parameters, such as specific impedance Z, isentropic compressibility κs, Rao's molar sound function Rm, van der Waals constant b, relaxation strength r, intermolecular free length Lf, internal pressure π, solvation number Sn, relative association RA, etc. are evaluated, which helps in understanding the molecular interactions occurring in these solutions.
