Ma, Yiming published the artcileSelective production of 2-(tert-butyl)-3-methylphenol from depolymerization of enzymatic hydrolysis lignin with MoS₂ catalyst, Product Details of C8H10O2, the publication is Catalysis Today, database is CAplus.

Low selectivity and complex product distribution are the main challenges for the utilization of lignin. Herein, the selective production of 2-(tert-butyl)-3-methylphenol (TBC), an antioxidant in the polymer industry, from depolymerization of enzymic hydrolysis lignin (EHL) on a hydrothermally synthesized MoS₂ catalyst is studied. The total aromatic monomer yield is 124.1 mg/g EHL and the selectivity of TBC is up to 40.3 wt% in methanol at 280 °C under 2 MPa H₂ for 6 h. The FT-IR anal. of products reveals that MoS₂ has a high activity for demethylation, dehydroxylation and alkylation, and the dimer conversions reveal that C-O and C-C bonds in EHL are broken with MoS₂. The guaiacol and its derivatives are identified as the intermediate for formation of TBC in EHL depolymerization according to the effect of time on product distribution and monomer conversion.

De la Rosa, Jose M. published the artcileImpact of Biochar Amendment on Soil Properties and Organic Matter Composition in Trace Element-Contaminated Soil, Synthetic Route of 91-16-7, the publication is International Journal of Environmental Research and Public Health (2022), 19(4), 2140, database is CAplus and MEDLINE.

The application of biochar as an organic amendment in polluted soils can facilitate their recovery by reducing the availability of contaminants. In the present work, the effect of biochar application to acid soils contaminated by heavy metal spillage is studied to assess its effect on the quantity and composition of soil organic matter (SOM), with special attention given to soil humic acids (HAs). This effect is poorly known and of great importance, as HA is one of the most active components of SOM. The field experiment was carried out in 12 field plots of fluvisols, with moderate and high contamination by trace elements (called MAS and AS, resp.), that are located in the Guadiamar Green Corridor (SW Spain), which were amended with 8 Mg·ha-1 of olive pit biochar (OB) and rice husk biochar (RB). The results indicate that 22 mo after biochar application, a noticeable increase in soil water holding capacity, total organic carbon content, and soil pH were observed The amounts of oxidisable carbon (C) and extracted HAs in the soils were not altered due to biochar addition Thermogravimetric analyses of HAs showed an increase in the abundance of the most thermostable OM fraction of the MAS (375-650°C), whereas the HAs of AS were enriched in the intermediate fraction (200-375°C). Spectroscopic and chromatog. analyses indicate that the addition of biochar did not alter the composition of the organic fraction of HAs, while Cu, Fe, and as were considerably accumulated at HAs.

Fraga, Gabriel published the artcileRole of Catalyst Support’s Physicochemical Properties on Catalytic Transfer Hydrogenation over Palladium Catalysts, COA of Formula: C8H10O2, the publication is ChemCatChem (2021), 13(24), 5191-5202, database is CAplus.

Catalytic transfer hydrogenation (CTH) is a promising reaction for valorisation of bio-based feedstocks via hydrogenation without needing to use H₂. Unlike standard hydrogenation, CTH occurs via dehydrogenation (DHD) of a hydrogen donor (H-donor) and hydrogenation (HYD) of a substrate. Therefore, the “ideal” CTH catalyst must balance the catalysis of both reactions to maximize the hydrogen transfer between H-donor and substrate with minimal H₂ loss to gas (high atom efficiency). Addnl., the H-donor must be highly stable to prevent secondary reactions with the substrate. Herein we study the impact of the catalyst’s properties on CTH of guaiacol using bicyclohexyl, a liquid organic hydrogen carrier, as a H-donor. The reaction was promoted by palladium dispersed on three typical support materials (γ-Al₂O₃, MgO, and SiO₂). The performance of these catalysts in the conversion of bicyclohexyl and guaiacol was evaluated, allowing to estimate the H-transfer efficiency, as well as the potential for recycling the spent H-donor (bicyclohexyl). The apparent activation energies for DHD of bicyclohexyl and HYD of guaiacol revealed that slow DHD combined with fast HYD, as is the case with Pd/MgO, favors hydrogen transfer efficiency and selectivity towards hydrogenated products. In addition, an investigation of the DHD of bicyclohexyl and HYD of guaiacol independently showed that the affinity between the organic mols. and the support significantly impacts CTH. Indeed, Pd/SiO₂ was highly active for both reactions individually and almost inactive for CTH. Consequently, these findings highlight the importance of the interaction between solvent-substrate-support in designing catalysts for transfer hydrogenation.

A new synthetic approach for fluorinated alkoxytriphenylene discotic liquid crystals is presented. This methodol. exploits the previously described photocyclodehydrofluorination (PCDHF) reaction for the preparation of fluorinated triphenylene derivatives coupled with a variety of nucleophilic aromatic substitution (S_NAr) reactions. This particular combination of reactions provides a versatile route to discotic materials with carefully controlled core fluorine and alkoxy tail content. In the course of these studies, new discotic materials with minimal tail content have been revealed. The mesogenic properties of these materials are reported, and their charge transport properties are measured using the time of flight technique.

Penland, Marine published the artcileBrine salt concentration reduction and inoculation with autochthonous consortia: Impact on Protected Designation of Origin Nyons black table olive fermentations, Related Products of ethers-buliding-blocks, the publication is Food Research International (2022), 111069, database is CAplus and MEDLINE.

Nyons table olives, named after the French city where they are processed, are naturally fermented black table olives. Their specificity relies on the use of the ‘Tanche’ olive variety harvested at full maturity and their slow spontaneous fermentation in 10% salt brine driven by yeast populations. This study aimed at investigating the benefit of inoculating autochthonous consortia to produce Nyons table olives by fermentation in 10% salt brine and in reduced salt conditions (8%). Two strategies were evaluated: inoculation with a defined autochthonous consortium and inoculation by spent brine backslopping. To define the consortium, yeasts were selected among 48 autochthonous isolates and key features included high halotolerance, low pectinolytic and proteolytic activities, however none had β-glucosidase activities. The consortium included eight yeast strains with distinct technol. properties belonging to five dominant species, i.e. Citeromyces nyonsensis, Pichia membranifaciens, Wickerhamomyces anomalus, Zygotorulaspora mrakii and Candida atlantica. Fermentation trials were conducted over a year and compared by evaluating microbial community shifts (16S and ITS metagenetics) and volatile profiles (GC-MS). Regarding fermentations with the defined consortium, four out of five species implanted in early stages while one, Pichia membranifaciens, persisted and largely dominated by the end of the fermentation Altogether, inoculation with the defined consortium did not disrupt microbial shifts compared to traditional fermentations although minor differences were observed in volatile profiles. The backslopping method yielded the highest impact on microbial populations and olive volatile profiles, with higher ester abundances at the end of fermentation Finally, reduced salt in brine gave very promising results as no deleterious effects on microbial communities, volatile dynamics but also safety criteria of the olives were observed compared to traditional fermented olives.

As a typical Chinese tea, Pu-erh tea attracts much attention due to its unique flavor formed by taste and aroma compounds To study the effects of taste compounds on the aroma release, model solutions containing five typical methoxyphenolic compounds (MCs) and main taste compounds with different concentrations were prepared based on the anal. of Pu-erh tea samples. GC-MS results indicated that the release of five MCs was inhibited by theabrownin, tea polysaccharide, tea polyphenol and catechins. The release of 1,2-dimethoxybenzene, 3,4-dimethoxytoluene and 1,2,3-trimethoxy-5-methyl-benzene was promoted by gallic acid under a low concentration (≤4 mg/g). Statistically, gallic acid had the most significant effect on the release of MCs. Isothermal titration calorimetry suggested that hydrogen bonds and hydrophobic effects had potential contributions to the interaction between taste and aroma compounds This work will provide the research basis for revealing the formation mechanism of tea flavor.
