abstract: |
Acetoxylation of toluene (Tol) to Benzyl acetate (BA) takes place in the presence
of acetic acid and O2. Pd based catalysts are known to be active for this system.
In this study, Pd-Sb/TiO2 catalyst pre-treated in helium showed 54 % of toluene conversion
and 89 % of BA selectivity with stability of 25 hours. The deactivated catalysts were
effectively regenerated at 300 °C/2h/air. Additionally pressure showed strong influence
on the performance. Acetoxylation with other substituted toluenes with varying electron
withdrawing and donating group were also successfully performed.
