apparent molar compressibility - Opis:
- Density (ρ), Sound velocity (U) and viscosity (ɳ) of pure solvent N,N-dimethylformamide (DMF) and solutions of pyrazolo quinazoline derivatives in DMF were taken at different concentration range and at different temperatures by using Antone paar. From these experimental data, some acoustical parameters such as adiabatic compressibility (κs), intermolecular free length (Lf), solvation number (Sn), apparent molar compressibility (fk), apparent molar volume (fv), internal pressure (π) etc., have been determined and correlated with the concentration (C).With concentration and temperatures, Linear or non-linear increases or decreases of acoustical parameters shows the existence of strong molecular interactions between solute and solvent. The results are interpreted in terms of solute-solute and solute-solvent interactions to understand the behavior of synthesized compounds in solutions.
