AI Article Synopsis
- The study focuses on creating cellulose triacetate from waste lignocellulosic parts of date palm, aiming to provide an eco-friendly alternative to petrochemical products.
- A heterogeneous acetylation reaction was used, achieving a degree of substitution of 2.9, resulting in a cellulose ester with 43.9% acetyl and a molecular weight of 205,102 g·mol.
- The synthesized cellulose triacetate has a thermal decomposition temperature of 380 °C, indicating its potential for use in biodegradable biocomposite materials.
Article Abstract
Cellulosic polysaccharides have increasingly been recognized as a viable substitute for the depleting petro-based feedstock due to numerous modification options for obtaining a plethora of bio-based materials. In this study, cellulose triacetate was synthesized from pure cellulose obtained from the waste lignocellulosic part of date palm ( L.). To achieve a degree of substitution (DS) of the hydroxyl group of 2.9, a heterogeneous acetylation reaction was carried out with acetic anhydride as an acetyl donor. The obtained cellulose ester was compared with a commercially available derivative and characterized using various analytical methods. This cellulose triacetate contains approximately 43.9% acetyl and has a molecular weight of 205,102 g·mol. The maximum thermal decomposition temperature of acetate was found to be 380 °C, similar to that of a reference sample. Thus, the synthesized ester derivate can be suitable for fabricating biodegradable and "all cellulose" biocomposite systems.
