摘要

Abstract The plot of rate constants vs. pH for the dehydration step of the reaction between furfural and 5-nitrofurfural with hydroxylamine, N-methylhydroxylamine, and O- methylhydroxylamine, shows two regions corresponding to the oxonium ion-catalyzed and spontaneous dehydration. The oxonium ion-catalyzed dehydration region of the reaction of furfural with the above mentioned hydroxylamines exhibits general acid catalysis with ...
