The paper covers the synthesis and characterization of cellulose derivatives from waste cellulose, namely, towel wastes. For this purpose, the cellulose acetate derivatives were synthesized from towel waste by applying the conventional chemical synthesis process. To clarify the structure of synthesized materials, some spectroscopic methods (FT-IR, XRD, 1 H-NMR, 13 C-NMR) were used. Furthermore, thermal behavior and surface morphology of prepared materials were investigated by DTG-TG and SEM, respectively. It was found that the degree of substitution values decreased as the duration of hydrolysis increased in cellulose diacetate synthesis. It was also understood that cellulose diacetate was dissolved in acetone differently from cellulose triacetate. Degree of substitution values of cellulose diacetate were compared by using 1 H-NMR and titrimetric method. These helped elucidate the expected reaction. The proposed method was easy compared with the conventional method.

“…The synthesis of CA in binary solvents of [DBNH][OAc] shows dispersants. Using five anhydrous glucose units (AGU) at 80 °C, DS of CA reached 2.68 within 0.5 h. Similar conditions, without the addition of a co-solvent, resulted in a DS of 0.9 after 3.0 h. The protic with amidine and acetic acid for cellulose dissolving found that [DBUH][OAc] had the greatest catalytic performance for cellulose acetylation [ 68 , 69 ]. The DS of CA increased from 2.61 to 2.87.…”

The latest advancements in cellulose and its derivatives are the subject of this study. We summarize the characteristics, modifications, applications, and properties of cellulose. Here, we discuss new breakthroughs in modified cellulose that allow for enhanced control. In addition to standard approaches, improvements in different techniques employed for cellulose and its derivatives are the subject of this review. The various strategies for synthetic polymers are also discussed. The recent advancements in polymer production allow for more precise control, and make it possible to make functional celluloses with better physical qualities. For sustainability and environmental preservation, the development of cellulose green processing is the most abundant renewable substance in nature. The discovery of cellulose disintegration opens up new possibilities for sustainable techniques. Based on the review of recent scientific literature, we believe that additional chemical units of cellulose solubility should be used. This evaluation will evaluate the sustainability of biomass and processing the greenness for the long term. It appears not only crucial to dissolution, but also to the greenness of any process.
