Abstract
N-(2-hydroxyethyl)ethylenediamine reaction was observed over zeolite c atalysts giving rise to only dehydrocyclization and over chromite cata lysts showing dehydrocyclization together with dehydrogenation. The ma jor product changes from the cyclized compound piperazine to pyrazine when the reactant is switched from zeolite to chromite catalyst. This process stands as a model reaction for characterizing lone acid sites and adjacent acid-base sites over zeolite and chromite catalysts, resp ectively.
