Deep Eutectic Solvents (DESs) are a class of solvents that increasing their relevance in the research activity thanks to environmental-friendly features as well structural characteristics and catalytic properties. Formed by no-solvent mixing two substances, namely hydrogen bond donor acceptor, DESs finding fruitful applications many different topics alternatives common organic compounds. In this work realization, characterization solubility novel water-based proposed. These innovative liquids, called aquo-DESs, binary mixtures water with glycolic acid (GA) trimethylglycine (TMG): GA:H2O (1:4 M ratio) TMG:H2O (1:5 ratio). The DES' identity these was demonstrated by: shifts both terms molar fraction melting points experimental point curves from theoretical ones; amounts components over reported maximum water; thermogravimetric profiles compared pure substances. aquo-DESs were characterized viscosity ionic conductivity temperature range 20–55 °C, showing really low conductivity, peculiar behavior DES. solubilizing properties aminoacids, phenols carboxylic acids showed high values whenever solute can participate DES component itself.

Abstract BACKGROUND The development of efficient and green pretreatment pathway is great significance for promoting biofuel production from lignocellulosic waste. purpose this work was to evaluate that iron ion‐catalyzed hydrogen peroxide can be used as an environmentally friendly way bio‐jet fuel using straw. RESULTS effects (Fe‐HP) on the enzymatic hydrolysis, fermentation straw were investigated. It found significantly improved hydrolysis efficiency biomass. Subsequently, directional catalytic transformation straw‐derived broth fuels achieved a dual functional catalyst (HSAPO34/NiHBET). High conversion (94.9%) good jet‐fuel selectivity (77.3%) obtained in process On account biomass characterization analysis reactive oxygen species during Fe‐HP pretreatment, role mechanism addressed. CONCLUSION jet increased sugar yield concentration which beneficial subsequent production. take prominent lignocellulose. © 2024 Society Chemical Industry (SCI).

In the context of cellulose valorization, we studied kinetics levulinates synthesis via solvolysis 5-HMF by alcohol over Amberlite IR-120. The plays a double role; it is reactant and acts as solvent. literature, kinetic models were developed for each type alcohol, but there no combining dual effect alkyl group substituent (ROH) Such global can save time optimize process considering solvent effect. This was taken into account Kamlet–Abboud–Taft Taft equations, using Bayesian inference. We levulinate production from in reaction mixture made GVL within temperature range 80 to 115 °C. following alcohols used: methanol, ethanol, propanol, butanol, pentanol, hexanol. It found that rate increases faster medium compared water medium, when increasing substitution (rMLMethanol>rELEthanol>rPLPropanol>rBLButanol>rPeLPentanol>rHeLHexanol>rLAWater). Among this study, one neglects side humins be most reliable.

This work aimed to extract nanolignin from green coconut husk and fiber using the acetosolv method, with aim of transforming waste into high-value-added products promoting sustainability bioeconomy. The pulping was carried out in two stages, varying temperature conditions presence or absence extractives. Lignin obtained by precipitation subsequently characterized through chemical morphological analyses. analyses primary components demonstrated lignin, cellulose, hemicellulose contents 40%, 15.90%, 15.86%, respectively. Then, produced ultrasonication (850 W for 10 20 min). characteristics were analyzed, considering influence temperatures (100 °C 120 °C) need a pretreatment step (removal extractives). variation between 100 °C, as well extractives, did not significantly lignin quality extraction efficiency. under this condition subjected DLS technique determine hydrodynamic diameter polydispersity nanoparticles obtained, an average 533.75 ± 15.12 nm after min ultrasonication. purity confirmed such Klason ash content, which presented values 78.82 0.81% 0.55 0.26%, FTIR revealed typical characteristics, ketone groups, aromatic structures, methoxylation, while thermograms thermal stability lignin.
