Base treated H-mordenite as stable catalyst in alkylbenzene transalkylation

Hierarchical K/LTL zeolites: Synthesis by alkali treatment, characterization and catalytic performance in Knoevenagel condensation reaction

“…23 Knoevenagel condensation of aldehyde or ketone with active 24 methylene group compounds to form bulky unsaturated products 25 (Scheme 1) is one of the most important base catalyzed reactions 26 involving C-C bond formation and plays a vital role in the synthesis 27 of fine chemical [3][4][5] and employed as a probe reaction for the 28 characterization of the basic catalysts [6,7]. The homogeneous 29 Knoevenagel condensation reaction is catalyzed by using various 30 liquid bases such as piperidine, amines, ammonia, and ammonium 31 salts [8].…”

“…51 Desilication is one of the promising post-synthesis modification 52 techniques by which the hierarchically structured zeolites with 53 intracrystalline mesoporosity can be synthesized owing to its 54 versatile, effective, scalable and green synthetic approach. The 55 scientific investigations have been increasingly focused on 56 desilication which involves the study of the hierarchically 57 structured zeolites [25][26][27]. overall procedure followed was reported elsewhere [31].…”

Hexane Isomerization over Hierarchical Pt/MFI Zeolite

“…Similarly, TPD of hexane isomers can be a quick test for probing subtle variation in micropore structures by means of desorption capacity and desorption temperature [16,23]. As shown in Fig.…”

Catalysis of Zeolite in the Amidation of Alcohols with Nitriles for the Synthesis of N-Alkylacrylamides

“…Introduction of mesoporosity into microporous zeolites can enhance diffusivity and thus improve their adsorption capacity [24] and catalytic properties [25][26][27][28][29][30][31]. Ritter reaction involves bulky alcohols and intermediates.…”
