Abstract

The acylation of phenol with acetic anhydride was carried out over different modified ZSM-5 catalysts. Co, Cu, and Ce showed a promoting effect. The best temperature and weight hourly space velocity for this reaction were found to be 250°C and 0.5 h−1, respectively. ZSM-5(30) was found to be a better catalyst than ZSM-5(150) and ZSM-5(250) in the acylation of phenol. A plausible reaction mechanism is also discussed.
