Deep eutectic solvents (DES), especially those derived from cholinium chloride ([Ch]Cl), have been studied as alternative for various chemical processes. Despite their widespread use, the understanding of possible formation impurities in these solvents, such esters, is still incomplete. In this study, thermal and long-term stability [Ch]Cl-based DES were investigated. Specifically, three with carboxylic acids (acetic acid, formic lactic acid - mixtures water The results show that formed [Ch]Cl: has lower stability, but addition to significantly reduces rate ester formation. acetic found exhibit good stability. However, disadvantage containing a significant amount lactide originally. It noteworthy esterification preparation only took place at temperatures up 40 °C no further formed, making it most suitable processes temperature. summary, choice appears influence formation, temperature accelerating reaction playing crucial role slowing long term, however, be unavoidable, continues even after its production. Therefore, investigating combinations, focus on content process, essential.

Lignocellulose biomass (LCB) is a plant mainly composed of cellulose, hemicellulose, and lignin. Cellulose the most abundant biodegradable polymer on Earth very useful for various applications. However, complex structure lignocellulosic biomass, in which cellulose tightly bound to hemicellulose lignin, poses significant challenges isolation from LCB components. This necessitates efficient pretreatment techniques enable separation. Conventional methods are not sustainable because they involve use harsh chemicals, elevated temperatures, high energy consumption, low productivity, formation fermentation inhibitors can increase cost processing with negative environmental impacts. Green have been proposed address these issues using milder more approaches. These green evaluated terms their delignification efficiency, reduced solvent requirement, impact, economic viability, relevance recent advancements technologies. review provides overview application environmentally friendly as well potential key feedstock bioeconomy by showcasing versatility industrial

Abstract This research aimed to study on nanocellulose production from palm bunch using process design and cost analysis. Choline chloride based deep eutectic solvent pretreatment was selected for high-purity cellulose separation at mild condition, followed by nano-fibrillation mechanical treatment. Three types of choline chloride-based solvents employing different hydrogen-bond donors (HBDs) namely lactic acid, 1,3-butanediol oxalic acid were studied. The optimal extraction condition chloride/lactic (ChLa80C) empty 80 °C bleaching yielding 94.96%w/w content in product. Size reduction ultrasonication high-pressure homogenization produced 67.12%w/w raw material. Different morphologies tunable the forms nanocrystals, nano-rods nanofibers dissimilar solvents. work offered a sustainable environmentally friendly as well provided analysis DES overview operating production. Application fabrication highly functional biodegradable material nanomedicine, electronic, optical, micromechanical devices is achievable near future.
