Resumen:
An efficient Co-ZSM-11 catalyst has been synthesized for benzaldehyde production by the selective styreneoxidation. Reaction parameters such as catalyst mass, reaction temperature, molar ratio styrene/hydrogenperoxide and stirring speed were optimized, by performing the styrene oxidation reaction in a stirred batchsystem with fine particles of Co-ZSM-11 in suspension under microwave heating. A kinetic study was done byusing the initial rates method and the Arrhenius parameters were estimated. This catalyst presents a higherreaction rate about 30% with respect of those found in literature and a higher selectivity towards benzaldehydeabout 80% at optimal conditions.
