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 K-s Rao's molar sound function R-m van der Waals constant b, relaxation strength r, intermolecular free length L-f, internal pressure pi, solvation number S-n, relative association R-Lambda, etc. are evaluated, which helps in understanding the molecular interactions occurring in these solutions.
