Der Reaktionsmechanismus der allgemeinen Säure—Basen-Katalyse der Mutarotation der Glucose, 12. Mitt.: Die Aktivierungsgrößen der durch Deuteriumionen katalysierten Glucose-Mutarotation in schwerem Wasser

The free enthalpy of activation, the enthalpy of activation and the entropy of activation of the deuterium ion catalysis of the mutarotation of α-glucose in deuterium oxide have been determined and compared with those of the deuterium oxide catalysis; furthermore they have been compared with the corresponding values of the hydrogen ion catalysis and of the water catalysis and the mechanism of activation of the studied catalysis has been elucidated.
