ACID-BASE EQUILIBRIA IN ACETYLACETONE: DISSOCIATION OF SOME WEAK ACIDS AND THE AUTOPROTOLYSIS CONSTANT OF THE SOLVENT

ACID-BASE EQUILIBRIA IN ACETYLACETONE: DISSOCIATION OF SOME WEAK ACIDS AND THE AUTOPROTOLYSIS CONSTANT OF THE SOLVENT

The dissociation and homoconjugation constants of 2, 5-dichlobenzenesulfonic, p-toluenesulfonic, methanesulfonic and picric acids have been determined at 25°C in acetylacetone by conductometry and potentiometry, and compared with those in other solvents. The autoprotolysis constant (Ks) of acetylace...

Zusammenfassung:The dissociation and homoconjugation constants of 2, 5-dichlobenzenesulfonic, p-toluenesulfonic, methanesulfonic and picric acids have been determined at 25°C in acetylacetone by conductometry and potentiometry, and compared with those in other solvents. The autoprotolysis constant (Ks) of acetylacetone was estimated potentiometrically with a glass electrode (pKs = 19.3).
