| Abstract: | The liquid phase of acetylation of 1,2-dimethoxybenzene with acetic anhydride has been investigated over a series of acid iron-mesoporous materials (Fe-MCM-41) synthesized by microwave irradiation method with different Si/Fe ratios (Si/Fe?=?80, 50, 10) and characterized by several spectroscopic techniques such as: N2 physical adsorption, ICP, XRD, TEM, FT-IR, and a temperature?Cprogrammed?Cdesorption (TPD) of pyridine. In fact, the catalyst Fe-MCM-41 (10) showed bigger performance in the acid-catalyzed acetylation of 1,2-dimethoxybenzene employing acetic anhydride as an acylating agent. Furthermore, the kinetics of the acetylation of 1,2-dimethoxybenzene over these catalysts have also been investigated. |
