    Extra-Large-Pore Zeolites with UTL Topology: Control of the Catalytic Activity by Variation in the Nature of the Active Sites

  • Original language description

    The catalytic behavior of isomorphously substituted B-, Al-, Ga-, and Fe-containing extra-large-pore UTL zeolites was investigated in the acylation of p-xylene with benzoyl chloride and Beckmann rearrangement of 1-indanone oxime. The clear synergism between the BrOnsted acidity (i.e., the concentration and the strength of protonic acid sites) of UTL catalysts and their activity in benzoylation was established. (Ga)UTL zeolite containing the BrOnsted acid sites of medium strength is characterized by theoptimum activity and selectivity in the benzoylation of p-xylene. Because of a higher accessibility of active centers, (Al)UTL zeolite appears to be a more active and selective catalyst than (Al)BEA in the benzoylation of p-xylene. In contrast to (B), (Ga), and (Al)UTL, the leaching of active sites occurs in the benzoylation over (Fe)UTL. All UTL zeolites showed 100% selectivity in the Beckmann rearrangement of 1-indanone oxime, which provides the target 3,4-dihydroquinolin-2(1H)-one. (B
