“…Oil resistance, wet slip resistance, damping, shock resistance, sealing, and other properties of ITA-based elastomers are outstanding [9]. The performance of ITA-based elastomers like DBI is comparable to that of standard styrene butadiene rubber [12] [13]. Due to such remarkable uses, DBI is expected to ful l the needs of the emerging industrial application and attract signi cant attention worldwide.…”

“…In general, three distinct categories of porous materials exist, microporous (< 2nm), mesoporous (2-50 nm) and macroporus (50-100nm). Among the various existing microporous materials, zeolites are increasingly gaining interest as solid acid catalysts in various organic reactions, ion-exchangers / water softening sorbents and gas storage materials [13]. Controllable acidity, composition, and uniform arrangement of pore structure of zeolites' cavities and channel system are key reasons for their widespread applications [14].…”

The current study concentrates on the synthesis of dibutyl itaconate (DBI) via esterification reaction of itaconic acid (ITA) and n-butanol over the synthesized novel hierarchical zeolite and the parent H-BEA acid catalysts. ITA is among the top platform scaffolds which are derived from biomass. DBI, has numerous industrial applications as, plasticizers, gelation accelerators, lubricants, antirust additives, adhesives, detergent additives etc. In the present study, tetradecyltrimethylammonium bromide (TTAB) surfactant is used as a structure directing agent and yeast as an additional modifier to create hierarchical zeolite H-BEA. Several characterization techniques [XRD, SEM-EDX, N2-sorption isotherms, NH3-TPD, FT-IR, solid-state NMR (27Al, 29Si, 1H)] were used to characterise the synthesized hierarchical structure involving both, microporosity and mesoporosity. Under optimal reaction conditions, hierarchical zeolite shows a higher % ITA yield as compared to its counterpart, parent H-BEA zeolite catalyst. This may be attributed to the enhanced physicochemical and catalytic properties of the resulting hierarchical zeolite catalyst.
