Potentiometric and Voltammetric Study of 6-Benzylaminopurine and Its Derivatives
Original language description
The protonation-deprotonation equilibrium of 6?benzylaminopurine (6?BAP) and its derivatives was studied by potentiometry and voltammetry. The effect of Cl or OCH3 group position in 2', 3' and 4' of the benzene ring of 6?BAP on both pKa values was investigated. To determine the enthalpy and entropy, the temperature dependence of pKa was employed. It was found that with increasing temperature the pKa decreased. In comparison with 6?BAP the chloro- or methoxy- group on the benzene ring resulted in pKa increase, and in the case of both derivatives the pKa values decreased with increasing distance of the chloro- or methoxy- moiety from the aminopurine structure. The first pKa values were also determined by linear sweep voltammetry (LSV) and elimination voltammetry with linear scan (EVLS). New approaches were shown not only for the determination of pKa from voltammetric titration curves but also for the evaluation of the reduction processes of benzylaminopurines.
