Adjusting the thermodynamic process is crucial for accelerating CaP crystallization and enhancing the energy efficiency. In this study, hydroxyl radicals (·OH) generated via an electro-Fenton-like system were employed to induce CaP crystallization. Experimental investigation and theoretical calculations revealed ·OH to be key for phosphate release and CaP crystallization. The interactions between ions and NTMP are effectively strengthened by ·OH-induced multiple hydrogen bonds, leading to intermolecular aggregation and the formation of amorphous clusters. These clusters can create thermodynamic conditions that are more conducive to crystallization. Therefore, ·OH-induced CaP crystallization predominantly proceeded through the formation of amorphous clusters as the intermediate state, representing a nonclassical crystallization process. The issue of electrode deactivation caused by surface scaling was effectively avoided when crystallization primarily occurred within the amorphous clusters, resulting in the formation of CaP crystals in bulk solution. The recovered CaP crystals showed the possibility of being used as phosphorus fertilizers based on plant experiments. Finally, ·OH-induced CaP crystallization was achieved during the authentic CW treatment. This research expanded the application of ·OH to CaP crystallization and provided a sustainable strategy for CW treatment.","PeriodicalId":25,"journal":{"name":"ACS Sustainable Chemistry & Engineering","volume":"111 1","pages":""},"PeriodicalIF":8.4,"publicationDate":"2025-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143031475","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this work is to prepare an innovative biobased vitrimer starting from the reaction between epoxy and acidic groups. The formulations are thermally cross-linked and then reprocessed by a transesterification reaction. The chemicals used are Cardolite NC-547, a biobased epoxy monomer synthesized from cardanol oil, and itaconic acid. Two catalysts are used: 2-ethyl-4-methylimidazole and zinc triflate. The first one mainly takes part in the cross-linking reaction, while the second one plays a role in both cross-linking and transesterification reactions. A conversion of 86% and a gel content of 82–84% are obtained when both catalysts are used. The thermal reprocessability of the cross-linked polymers is verified by mechanical tests, and the properties of the reprocessed vitrimers are compared with those of the virgin materials. Results show that a good reprocessability is obtained, with no significant change in conversion and gel content values, when a proper amount of zinc triflate is used. A slight increase in cross-linking density values and mechanical properties is observed after reprocessing. A preliminary life cycle assessment (LCA) is performed with the aim of guiding research with relevant environmental information. LCA results suggest that biobased vitrimers could lead to the production of more sustainable products compared to fossil-based ones.","PeriodicalId":25,"journal":{"name":"ACS Sustainable Chemistry & Engineering","volume":"63 1","pages":""},"PeriodicalIF":8.4,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143031477","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent investigations demonstrated a biobased pathway to prepare the platform chemical 4,4′-dimethylbiphenyl (4,4′-DMBP). The synthesis of 4,4′-DMBP follows a two-step process: (1) 2-methylfuran (2-MF) oxidative coupling to 5,5′-dimethyl-2,2′-bifuran (5,5′-DMBF) and (2) 5,5′-DMBF tandem Diels–Alder-dehydration with ethylene to afford 4,4′-DMBP. Here, we report the intensification of reaction conditions in step (1), improving 5,5′-DMBF space-time yield up to 1.10 mol L<sup>–1</sup>h<sup>–1</sup>, an 86% increase from the baseline. Scale-up of step (1) was hindered by oxygen-deprivation-induced palladium black formation and reaction exotherms decreasing yields at larger scales. Oxygen sparging, mechanical mixing, and internal cooling implemented simultaneously enabled a 108× increase in 5,5′-DMBF production to an average of 13 g/batch. In step (2), the use of a homogeneous La(OTf)<sub>3</sub> catalyst in the Diels–Alder-dehydration reaction─instead of heterogeneous γ-Al<sub>2</sub>O<sub>3</sub>─led to a 54% increase in 4,4′-DMBP yield with a 70 °C temperature reduction to 180 °C. Scale-up of the Diels–Alder-dehydration to 3 g/batch maintained <i>para</i>-selectivity for 4,4′-DMBP with full conversion to the product within 20 h.

The need for eco-friendly scale inhibitors for high-pressure, high-temperature (HPHT) applications has risen due to offshore regulations. This study investigates phosphonated Inulin (PIn), a modified biopolymer, as an eco-friendly scale inhibitor against calcite, gypsum, and Barite in harsh environments. Inulin, a natural polysaccharide, was functionalized with phosphonate groups, achieving a degree of substitution (DS) of 48.78%. Characterization through NMR and FTIR spectroscopy confirmed the successful modification. The scale inhibition effectiveness of PIn was tested in high-pressure dynamic tube-blocking tests at 100 °C and 80 bar compared to commercial carboxymethyl inulin (CMI). PIn effectively inhibited calcite and gypsum at 5 ppm under dynamic conditions and showed excellent thermal stability after 7 days at 130 °C, along with compatibility with high calcium ion concentrations, though it had minimal impact on barite scale. Molecular simulations offered insights into the morphology of the functionalized polysaccharides with GFN2-xTB MD simulations indicating a transition to a more compact structure. DFT analysis revealed that hydrogen bonds from phosphonate groups are stronger than those from hydroxyl or carboxylic groups, explaining PIn’s higher thermal stability compared to CMI.","PeriodicalId":25,"journal":{"name":"ACS Sustainable Chemistry & Engineering","volume":"7 1","pages":""},"PeriodicalIF":8.4,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143020157","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The scrutinized ions have been specifically chosen to allow for unraveling preferential interactions of functional groups that may favor or disfavor crystallization with respect to secondary bonding interactions, i.e., primary and quaternary ammonium cations of variable alkyl chain lengths, which were also endowed with hydroxy groups, combined with formate and bis(trifluoromethanesulfonyl)amide anions. The background is to provide a deeper fundamental understanding of how to intentionally pair cations and anions that will not support the formation of a crystalline solid but rather IL formation, an approach described as “anti-crystal engineering”. This concept is based on the idea to avoid combining ions that are strong supramolecular synthons for crystallization. To this avail, the crystallization behavior of salts constituted of combinations of selected ions bearing different structural, supramolecular crystallization motifs has been studied in detail by low-temperature differential scanning calorimetry (DSC). Single crystal X-ray structure analysis has been used to elucidate ion packing and preferential interactions whenever crystalline solid formation is observed. The study reveals that the lowest melting points are supported by cation–anion combinations that have the least hydrogen bonding. However, if there are multiple possibilities of H-bonding for an ion with its counteranion, this bonding frustration leads as well to low melting points–albeit they are still higher compared to ion combinations with no H-bonding capacity. Through a careful balance of primary and secondary, directional and nondirectional interactions, it was possible to rationally identify a record class of ionic liquids, which combine exceptionally high decomposition points (440–450 °C) with an enormously high liquid range around of more than 500 °C and no tendency for solidification down to well below ambient temperature (−90 °C). These ILs are formed by bis(trifluoromethane)sulfonylamides with quaternary ammonium ions that bear an −OH group in the side chain.","PeriodicalId":25,"journal":{"name":"ACS Sustainable Chemistry & Engineering","volume":"74 1","pages":""},"PeriodicalIF":8.4,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143020159","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The spent Na<sub>2</sub>SO<sub>4</sub> solution undergoes a simple treatment before re-electrolysis, achieving a closed-loop system with minimal waste generation and reduced reliance on external reagents. Moreover, the acid-leaching carbon residue is repurposed as a bifunctional carbon-based catalyst for hydrogen peroxide production.
