Abstract
This study investigates the extraction and acetylation of cellulose from Sporobolus pyramidalis, commonly known as Giant Rat Tail Grass, an abundant yet underutilized plant species. Cellulose was extracted through a series of chemical treatments, including alkali and bleaching processes, to remove lignin, hemicellulose, and other non-cellulosic components. The extracted cellulose was
characterized using Fourier-transform infrared spectroscopy (FTIR), which showed peaks closely matching those of commercial cellulose. Scanning electron microscopy (SEM) was also employed to confirm the structure of the extracted cellulose. The cellulose was then acetylated using acetic anhydride and sulfuric acid to enhance its thermal stability, hydrophobicity, and solubility. FTIR analysis confirmed the successful acetylation, with peaks closely aligning with those of commercial cellulose acetate. The acetylated cellulose exhibited improved properties, including enhanced solubility in organic solvents and thermoplasticity, making it suitable for use in bioplastics, coatings, and other biodegradable materials. This research highlights the potential of Sporobolus pyramidalis as a renewable source of cellulose and contributes to the development of sustainable, biomass- based materials.
