Abstract
Mesoporous Al-MCM-41 molecular sieve materials with three different SiO2/Al2O3 ratios were used as catalysts for the acetylation of phenol with acetic anhydride and acetic acid as the acetylating agents. The reactions gave 100% ortho-selectivity with acetic acid being the more effective acylating agent. The reactions were run under different conditions of temperature, feed flow rate, reactant mole ratio and SiO2/Al2O3 ratio of the catalyst and all the variables were shown to have significant influence on the acetylation of phenol. A possible reaction mechanism is also suggested.
