Journal Article 2024 02 03 Natural mesolite type zeolite was collected, modified by sulfuric acid treatment and characterized by using Powder-X ray diffraction (XRD), Scanning electron microscopy (SEM), Energy dispersive spectroscopy (EDS), Fourier transform infrared spectroscopy (FT-IR).Temperature programmed ammonia desorption (NH3-TPD), Brunauer-Emmer-Teller (BET) surface area analysis.  Modified dealuminated mesolite shows an efficient catalytic activity for the one-pot synthesis of quinoline-3-carbonitrile derivatives, via three-component cyclocondensation of benzaldehyde, malononitrile and aniline.  The present method offers several advantages over the reported methods like simple and inexpensive modification of the catalyst, mild reaction conditions and easy separation of the catalyst, simple work-up procedures, non-chromatographic separation and purification of desired product, excellent yield and reusability of the catalyst.
