Preparation and Characterization of Double Activity Sulfate-Gallate Bagasse Xylan

The objective of this research was to introduce another kind of anti-biological activitiy group to xylan sulfate for improve performance in anti-biological activitiy. A novel double activity sulfate-gallate bagasse xylan was prepared by using bagasse xylan as raw material, sodium nitrilotriacetic sulfonate and gallic acid as esterifying agents. The structure of product was characterized by FT-IR and SEM. The results show that the bagasse xylan was modified successfully, and the final product is a novel double activity sulfate-gallate bagasse xylan.
