Dehydrogenation and Diels-Alder reactions in a one-pot synthesis of benzaldehyde from n-butane over acid catalysts Article uri icon

abstract

  • VOx/ZrO 2/SiO 2 catalysts were synthesized via grafting of vanadium and zirconium alkoxides over Aerosil 380. With these materials the formation of benzaldehyde from butane was possible in a one-pot synthesis, where oxidative dehydrogenation (ODH) for the formation of butadiene is coupled with a Diels-Alder reaction for the formation of benzaldehyde. Experiments performed with a catalyst where the support was modified with Ce instead of Zr, give a material that under the reaction conditions studied does not yield benzaldehyde, showing that acidity plays an important role in the formation of this compound. © 2012 Elsevier B.V.
