The activity, selectivity, and stability of microporous highly dispersed zeolites (H-Y, H-ZSM-5) and granulated hierarchical zeolites (H-Y h and H-ZSM-5 h ) were studied in the synthesis of quinolines by the Skraup reaction. Texture, porous structure, morphology of crystals, acidic properties were characterized by XRD, XRF, N 2 adsorption-desorption, SEM, NH 3 -TPD methods. It was found that quinoline, 2-and 4-methylquinolines are the main products in the reaction of aniline with glycerol in the presence of the studied catalysts. H-ZSM-5 h and H-Y h catalysts are more efficient than catalysts H-ZSM-5 and HY and provide a yield of quinolines to 72.4 (H-ZSM-5 h ) and 60.2 % (H-Y h ) at 450 °C, 0.2 h À 1 , the molar ratio of aniline:glycerol = 1 : 3. The high activity and selectivity of hierarchical zeolites are due to the presence of meso-and macropores, as well as nanocrystals of 15-100 nm size. It was reported that hierarchical catalysts exhibit higher stability in the reaction compared with microporous zeolites.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
