Generation of Brønsted Acid Sites on Alumina-supported Tantalum(V) Oxide Calcined at 1223 K
An alumina-supported tantalum(V) oxide (Ta2O5/Al2O3) calcined at 1223 K promoted the Friedel–Crafts alkylation of anisole with benzyl alcohol, and exhibited Brønsted acidity despite the high-temperature calcination. Among the Ta2O5/Al2O3 catalysts tested, 33 wt % Ta2O5/Al2O3 calcined at 1223 K showe...

Zusammenfassung: | An alumina-supported tantalum(V) oxide (Ta2O5/Al2O3) calcined at 1223 K promoted the Friedel–Crafts alkylation of anisole with benzyl alcohol, and exhibited Brønsted acidity despite the high-temperature calcination. Among the Ta2O5/Al2O3 catalysts tested, 33 wt % Ta2O5/Al2O3 calcined at 1223 K showed the highest activity. |
