چکیده مقاله:
In this investigation H-mordenite zeolite has been shown to be an efficient, rapid, green, stable, chemoselective and recyclable catalyst for the synthesis of 1,1-diacetates (acylals) of various aromatic aldehydes under solvent-free conditions at room temperature. The main advantages of this protocol include low catalyst loading, shorter reaction time, excellent yields, ecofriendly, mild-condition, easy work-up procedures and reusable catalyst. This method must be useful in future for the synthesis of similar derivatives. The synthesized zeolite was characterized by various techniques via X-ray diffraction (XRD), scanning electronic microscopy (SEM), fourier transform-infrared (FTIR spectroscopy) and brunauer–emmett–teller (BET) surface area analysis. The synthesized reaction products were characterized by FTIR and 1H NMR technique. Further investigation of the application of H-MOR zeolite for other reactions is ongoing in our laboratory.
