The oxidative dehydrogenation reaction over an acid-base catalyst may partially proceed by simple dehydrogenation and partially by oxidative dehydrogenation hence two mechanistic paths were suggested one relating to simple dehydrogenation and the other combined with carbon dioxide. In general the acidic ...

MEA is preferentially adsorbed from the side of the hydroxyl group, which is then dissociated on acid and base sites of the catalyst simultaneously, and the consecutive dehydration occurs to form EI. The newly developed vapour phase process using these catalysts has been operated in the commercial...
