Micro-mesoporous sieves MCM-41 with different pore diameters were synthesized under microwave irradiation, characterized by X-ray diffraction, scanning electron microscopy, Fourier transform infrared spectroscopy, N2 adsorption–desorption and temperature-programmed desorption of NH3 (NH3-TPD). Intramolecular cyclization of N-Phenylanthranilic acid to acridone catalyzed by MCM-41 with different pore diameters was investigated. The results indicate that the yields increased significantly with the decrease of pore diameter of MCM-41. Furthermore, the yield of acridone under microwave irradiation was higher than that under conventional heating.
