“…The activation of cellulose using acetic acid before undergoing acetylation reaction is highly dependent on the amount of acetic acid used. It helps to trigger the expansion of the cellulose structure resulting in higher surface area and breakage of cellulose bonding (Tristantini and Sandra 2018). The formation of particle of CA increased in both size and number in increasing acetic acid.…”

“…Cellulose is activated when mixing with acetic acid, then the mixture is further acetylated with acetic anhydride with the presence of sulfuric acid as a catalyst. Activation of cellulose with acetic acid expands the cellulose structure which increases the reactive surface area and weakens the intermolecular hydrogen and hydroxyl bond of the cellulose (Tristantini et al 2018). This subsequently facilitates the binding of cellulose with the acetyl group from acetic anhydride during the acetylation process of CA formation.…”

“…This subsequently facilitates the binding of cellulose with the acetyl group from acetic anhydride during the acetylation process of CA formation. The acetylation process could be speeded up by adding sulfuric acid as a catalyst (Tristantini et al 2018). Due to the outstanding chemical, physical and mechanical properties of CA (Egot and Alguno 2018), it has been applied widely in various types of productions such as lms, coating, membranous lters, textiles, food packaging, pharmaceuticals and cosmetics (Fischer et al 2008;Cheng et al 2010;Hindi and Abohassan 2015).…”

Cellulose acetate (CA) was produced from cellulose through activation and acetylation reactions. This study focused on using kapok cellulose as the starting material in converting cellulose into CA as the final reaction product. In the production of CA from kapok cellulose, acetic acid was used to activate the cellulose before acetylating it with acetic anhydride and sulfuric acid. A total of 27 experiments with varying acetic acid amounts (17.5, 20, 22.5 mL), acetic anhydride (5, 7.5, 10 mL) and acetylation reaction time (30, 45, 60 min) were designed to evaluate CA formation. Fourier transform infrared spectroscopy was used to evaluate the CA formation by identifying its present functional group. The analysis showed that CA produced from 20 mL acetic acid, 10 mL acetic anhydride and 60 min acetylation reaction time as the highest peak intensities of the three major functional groups (C = O, C-H, and C-O). This indicated that CA formed from this condition has the strongest acetyl bonding among the conditions. Scanning electron microscopy evidenced the CA formation, yet they varied with different amounts of acetic acid, acetic anhydride and acetylation reaction time.

“…Lignin must be removed, to obtain cellulose with high purity through the delignification process. 20 The delignification process can be carried out using physical, chemical, physicochemical and biological methods. 21 Biological or enzymatic methods cannot be applied directly to lignocellulosic raw materials because lignin inhibits the penetration of fungi or enzymes into the cell walls of the lignocellulosic material.…”

Background: Lignocellulosic biomass is one of the materials that has the potential to produce cellulose. Lignocellulose material consists of lignin, hemicellulose and cellulose so that the three materials must be separated first to get pure cellulose. The main problem faced in the process of separating cellulose is the difficulty of separating lignin. One of the processes in separating lignin is by pretreatment of lignocellulosic material. Methods: In this study, Deep Euteutic Solvent (DES) choline (ChCl) as a hydrogen bond acceptor was synthesized and eight hydrogen bond donors (HBD) were mixed. Eight types of DESs, i.e. , choline chloride-acetic acid (ChCl-AA), ChCl: formic acid (ChCl-FA). ), choline chloride: Lactic acid (ChCl-LA), choline chloride:Citric acid (ChCl-SA), choline chloride: Glycerol (ChCl-G), choline chloride: Ethylenglycol (ChCl-EG), choline chloride: Sorbitol (ChCl-S), and choline chloride: Urea (ChCl -U) with a ratio of 1: 2 were investigated. Each. DES solvent was applied as a pretreatment for the lignocellulosic material of pineapple leaves. The results of the pretreatment formed were characterized by the Infra Red spectroscopic method to determine the typical functional groups. Result: The results showed that the pretreatment process using DES solvent resulted in a decrease in lignin levels in pineapple leaf powder, the highest in DES with linear saturated acid-based HBD, formic acid at 32.05%, glycerol at 30.18% and then in alpha hydroxy-based HBD, acetic acid at 29.90%. Meanwhile, the FT-IR results show that ChCl-FA has a high delignification ability during pretreatment. Pineapple leaves that have been pretreted with DES solvent can be a potential raw material for the next conversion process. This study presents DES as an effective and easy pretreatment method for lignin extraction.

“…The green synthesis approach, exploiting plant extracts as reducing agents, offer cost—and eco-friendly alternatives to the physical and chemical methods of synthesis. Several studies have reported the synthesis of cellulose using jackfruit leaves [ 8 ], Retama raetam [ 9 ] and Citrullus lanatus [ 10 ] as capping agent. In this present study, cellulose was synthesized from Sesamum indicum , an oilseed crop cultivated in Nigeria.…”

It has also become increasingly necessary to diversify the production of cellulose for biomedical applications. In this study, cellulose-green-synthesized from Sesamum indicum (GSC)—was administered orally to rats for 14 days as follows: control, 100, 200 and 400 mg/kg GSC. The impact of GSC on the antioxidant status and histomorphology of the testes and epididymis were studied. GSC had no effects on organ weights and organosomatic indices. In the testes, GSC caused nonsignificant changes in superoxide dismutase, catalase, reduced glutathione and nitric oxide levels, whereas it significantly decreased glutathione peroxidase and malondialdehyde levels. In the epididymis, GSC significantly decreased superoxide dismutase and nitric oxide levels, but caused a significant increase in glutathione peroxidase and reduced glutathione levels. Furthermore, at ×200 magnification, testicular morphology appeared normal at all doses, however, extravasation of the germinal epithelium of the epididymis was observed at doses of 200 and 400 mg/kg GSC. Conversely, at ×400 magnification, spermatogenic arrest (testes) and chromatolytic alterations (epididymis) were observed at the higher doses (200 and 400 mg/kg GSC). This study reports on the effect of green-synthesized cellulose on testicular and epididymal histology and redox status and further extends the frontiers of research on cellulose.
