Abstract

 The Acidity constants of some synthesized protonated pyrazolo quinazoline compounds were determined potentiometrically at ionic strength of 0. 1 M in DMF: water (60: 40 v/v) system at different temperatures (298. 15 K to 318. 15 K). The pKa values have been found to increase with increasing electron-donating nature of substitutions. Some thermodynamics parameters such as enthalpy (Δ H° ), Gibb’ s free energy (Δ G° ) and entropy (Δ S° ) of reactions have also been evaluated at different temperatures for these systems. The thermodynamic parameters indicate that dissociation process is not spontaneous and exothermic.
