In order to clarify the equilibrium mechanism of furfurylidene-INAH in aqueous solution, equilibrium constants of furfurylidene-INAH and 1-benzoyl-2-furfurylidenehydrazine in buffer solutions of various pH were measured. It was found that the variation in the resonance structure of furfurylidene-INAH in acidity had no direct effect on equilibrium constants but an effect on the ionic dissociation constant of its azomethine group.
