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.
