CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishThe influence of the reaction conditions and some aspects of the reaction network and changes in surface reactivity during the catalytic reaction in the selective oxidn. of 1-butene to 2-butanone (Me Et ketone, MEK) over supported Pd/V2O5 based catalysts at reaction temps. of around 120° are reported. In particular, the change in the selectivity to MEK as a function of time-onstream, the effect of a higher temp. treatment, the influence of the 1-butene, O2 and H2O concns. and the reaction temp., the nature of the support and the surface reactivity of MEK are shown. It is suggested that the catalytic behavior of Pd/V2O5 on alumina catalysts, characterized by the presence of a max. in the yield and selectivity to MEK, derives from the presence of a rate controlling effect of the desorption of MEK.
