Description
| - The effect of the concentration of Lewis acid sites on the activity and selectivity of different molecular sieve catalysts was investigated in the Friedel-Crafts acylation of ferrocene with acetic anhydride, toluene with isobutyryl chloride, and cyclohexene and 1-methylcyclohexene with propionic anhydride. H-, Zn-, Fe-, Al-, and La-forms of mesoporous molecular sieves (Al)MCM-41 and (Al)SBA-15 were studied and compared with large-pore zeolites. No general relationship between the type of cation and conversion of substrate was found. In acylation of ferrocene the highest ferrocene conversions were reached over Zn- and H-atoms while in toluene acylation Al-forms were the most active. The selectivities over mesoporous molecular sieves were lower (61-89 %) compared with zeolites (82-98 %).
