Noteworthy attributes of this protocol include excellent yields (up to 94%), ecological compatibility, and sustainability, rendering it advantageous from a synthetic standpoint. Green chemistry facets were integrated into the methodology, affirming its adherence to sustainable synthesis practices and highlighting its environmental friendliness. The characterization of the synthesized compounds was accomplished through comprehensive spectroscopic techniques, encompassing FT-IR, ¹H-NMR,¹³C-NMR, mass spectrometry, and elemental analysis. Furthermore, a quantum computational investigation was conducted employing density functional theory at the B3LYP/6-311G++(d,2p) level to elucidate chemical reactivity parameters. Remarkably, the HOMO–LUMO behavior was examined to ascertain the energy gap and molecular electrostatic potential of the synthesized compounds, thereby offering insights into their electronic structure and reactivity. In addition, a correlation between theoretical predictions and experimental observations were established, enhancing the credibility of the findings.

The CEDI method was used to enhance the electrostatic adsorption of nickel precursor onto the ceria support during dry impregnation (DI), hence charge-enhanced dry impregnation. The other ceria-supported nickel-based catalyst (labelled 10Ni/CeO₂-DI) was prepared by the commonly used DI method and used as the reference catalyst. The catalysts were then tested for stability and catalytic performance (biogas conversion and syngas yield) under biogas reforming conditions using CatLab-QGA equipment supplied by Hidden Analytical. The characterisation studies: X-ray diffraction (XRD), N₂ adsorption/desorption, X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), transmission electron microscopy (TEM), oxygen temperature programmed oxidation (O₂-TPO), temperature programmed reduction (TPR), and H₂-chemisorption were performed on the fresh and spent catalysts to gain insight into the influence of the CEDI method on dispersion, nanoparticles size of the active phase, metal-support interaction, bulk composition, and phase composition. The results showed that enhancing electrostatic attraction during the DI method produced 10Ni/CeO₂-CEDI with smaller nanoparticles (3.33 nm), improved nickel dispersion from 1.40 to 5.04% and improved metal-support interaction inferred from TPR values increased from 290 to 340 °C.

The ring opening of ethylenediaminetetraacetic acid dianhydride (EDTADA) by piperazine, a bifunctional cyclic secondary diamine, was conducted in a polar solvent (DMF) in a nitrogen atmosphere for 3 h. The characterization was conducted by FTIR and NMR analysis. The morphology and elemental composition were investigated by field emission scanning electron microscopy and energy-dispersive X-ray (FESEM-EDX). As-synthesized aliphatic tertiary poly(amic acid) could be separated as a white powder with an O/N ratio of 0.93 and morphology of woven fiber. The white powder showed an average molecular weight (M̅w) of ∼12,000 and a polydispersity index (PDI) of 1.52 ± 0.05. In addition, the poly(amic acid) TGA/DTA analysis showed a high thermal stability with stepwise degradation with the onset of 346 °C. The poly(amic acid) DSC profile displayed a high glass transition at 124 °C. The Brunauer–Emmett–Teller (BET) surface area and pore volume were determined to be 146.05 m²/g and 0.78 cm³/g. The poly(amic acid) contains the mesopores and macropores based on its pore size distribution curve. Regarding an acidic pH and abundance of functional groups, as-prepared tertiary poly(amic acid) was employed as a heterogeneous catalyst for preparing 3,4,5-trisubstituted furan-2-ones in ethanol. A conversion of 100% and pure products could be isolated in good to excellent yields directly from ethanol. No remarkable loss of catalytic activity was observed in the recycling of the catalytic system even after the 5th recycling. A gram scale of model reaction gave an 82% yield of the respective product. Therefore, 3,4,5-trisubstituted furan-2-one derivatives could be prepared in the laboratory and gram scale by an energy-, cost-, and time-saving strategy with a halogen-free and metal-free heterogeneous catalyst.</p><h3 data-test=\"abstract-sub-heading\">Graphical abstract</h3>\u0000","PeriodicalId":753,"journal":{"name":"Research on Chemical Intermediates","volume":null,"pages":null},"PeriodicalIF":3.3,"publicationDate":"2024-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142177372","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
