Abstract: Keto-enol equilibrium constants, KE, were determined for five aliphatic ketones (2- butanone, 3-methyl-2-butanone, 3, 3dimethyl-2-butanone, 3-pentanone, and 2, 4dimethyl-3- pentanone) and three alicyclic ketones (cyclopentanone, cyclohexanone, and cycloheptanone) in aqueous solution at 25 OC by combining acid-catalyzed enolization and ketonization rate constants according to the relationship KE= kE/kK. Enolization rate ...
