Synthesis and Characterization of Crosslinking Etherification Bagasse Xylan

摘要

The bagasse xylan is a polysaccharide that occurs in nature in enormous amount in various one year- and perennial plants. Versatile ways to generate bio-based functional polymers result from the chemical modification of this biopolymer. The crosslinking etherification bagasse xylan(CEBX) has been synthesized by using aqueous solution polymerization method. It implies the use of sodium hydroxide, chloroacetic acid as a carboxymethylating agent and epichlorohydrin as crosslinking agent. The DS values of Carboxymethylated xylan up to 0.59 can be controlled by adjusting the molar ratio in a two step syntheses. Crosslinking etherification bagasse xylan are water soluble at a DS of 0.3. The result showed that the final product had excellent surface activity. IR spectrometry were applied to characterize the carboxymethyl xylans in detail, and revealed characteristic absorption peaks at 1600, 1426 and 1324cm~(-1).
