S. R. Rajasekhar Pullabhotla, Auteur ; S. B. Jonnalagadda, Auteur Année de publication : 2010 Article en page(s) : pp. 9097–9105 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Metal  loaded  microporous  materials  n-hexadecane Résumé : The saturated hydrocarbons, alkanes, are known to exhibit extremely low reactivity, and reactions are feasible only at high temperature and pressure conditions. The scope of metal loaded microporous materials, ZSM-5, as catalysts in the ozone initiated oxyfunctionalization of n-hexadecane is investigated at 20 ± 1 °C and ∼1 atm. The efficiencies of 0.5% Pd, Ni, and V loaded microporous ZSM-5 catalysts on ozonation of n-hexadecane, with respect to the conversion, reaction products, and selectivity were compared. This paper emphasizes that the “Catazone” process of long chained alkanes to their corresponding 4-, 3-, and 2-keto products at moderate conditions is of significance, in that hitherto unreactive n-alkanes can be functionalized via ozonation catalytically.
