Summary
Several pyrazylmethyl ketones have been investigated in regard to their potential analytical utility as chelating agents for metal ions. Proton dissociation constants of the ligands and metal chelate formation constants were calculated from potentiometric data using the method of Irving and Rossotti. Chelate formation constants obtained in this study allow comparisons to be made between pyrazylmethyl ketones and other chelating agents possessing similar structures. The potential analytical utility of the title compounds is discussed.
Zusammenfassung
Einige Pyrazylmethylketone wurden auf ihre Fähigkeit zur Chelatbildung mit Metallionen untersucht. Die Protonendissoziationskonstanten der Liganden und die Chelatbildungskonstanten wurden aus potentiometrischen Daten berechnet, die nach Irving und Rossotti ermittelt wurden. Die Chelatbildungs-konstanten der Pyrazylmethylketone wurden mit denen ähnlich strukturierter Chelatbildner verglichen. Die analytische Brauchbarkeit der untersuchten Ketone wurde diskutiert.
