Zeolites have been used as an excellent and highly efficient catalyst for one tri substitut of benzil, aldehydes and ammonium acetate under mild conditions. The synthesized zeolites were characterized by various techniques such as Fourier Transform diffraction (XRD), Scanning electronic Microscopy (SEM). The synthesized products were characterized by FT with high to excellent yields. Furthermore, the ca for at least three times. ed imidazoles under solvent-free conditions. This route involves multicomponent reaction -Infrared S -IR and proton 1H NMR. This process was simple and environmentally benign talyst could be recovered conveniently and reused -pot synthesis of 2, 4, 5- pectroscopy (FTIR), X-Ray
