In recent years there is a growing urgency to develop renewable biodegradable materials for various applications, and to replace petroleum-based materials. This study aims to extract cellulose as raw material from Sudanese sugarcane bagasse (SCB) to prepare cellulose esters. The (SCB) sample was collected, grounded, dewaxed, delignified, purified and resolved in (DMA/LiCl) solvent system at 160°C. Then, cellulose esters were prepared by long chain acid chlorides namely hexanoyl (C6), octanoyl (C8), decanoyl (C10), in the presence of triethylamine for proton capture at optimum reaction condition. The produced cellulose esters were characterized using different instruments and methods. Elemental analysis was carried out to confirm the degree of substitution (DS). Fourier transfer Infra-Red spectroscopy (FT-IR) provide evidence of acylation by the presence of ester carbonyl groups and decrease of the band of the hydroxyl group. Thermo gravimetrical analyzer (TGA) showed that the prepared esters have different thermal stability depending on DS value and chain length at the substitution position. Solubility test shows different solubility of prepared cellulose esters depending, in addition to DS value, on the effect of the substituents on the hydrogen bonds. The study concluded that significant changes occur in the structure, thermal stability, and solubility of cellulose by esterification and the produced esters can be more useful than pure unmodified cellulose.
