Embodiment

[0048] (1) A certain amount of bagasse xylan is dried in a vacuum constant temperature drying oven at 60° C. for 24 hours to a constant weight to obtain dry-based bagasse xylan.

[0049] (2) Weigh 5.0 g of bagasse xylan obtained in step (1) and add it to a 250 mL four-necked flask, and add 25 mL of distilled water, and fully stir at 60° C. for 20 minutes.

[0050] (3) Weigh 0.5 g of ammonium persulfate and 0.8 g of sodium bisulfite in a beaker, then add 25 mL of distilled water, and stir evenly to obtain an initiator solution.

[0051] (4) Pour the mixed solution of the initiator obtained in step (3) into a constant pressure dropping funnel, and drop the mixed solution of the initiator in the system obtained in step (2), and control the addition in 4.5 to 6 hours.

[0052] (5) Weigh 5.0 g of acrylamide (AM) into a beaker, then add 20 mL of distilled water into the beaker, and stir evenly to obtain a monomer solution.

[0053] (6) Pour the monomer solution obtained in step (5)...

Abstract

The invention discloses a synthesis method of bioactive derivative bagasse xylan syringic acid ester-g-AM. The synthesis method comprises the following steps: by taking bagasse xylan as a starting rawmaterial, taking ammonium persulfate as an initiator, taking N,N'-methylene bisacrylamide as a crosslinking agent, preparing bagasse xylan-g-AM in a water-phase solution; then by taking the bagasse xylan-g-AM as a raw material, taking syringic acid as an esterifying agent and taking the ammonium persulfate as a catalyst, preparing the bagasse xylan syringic acid ester-g-AM in a solvent N,N-dimethylacetamide (DMA). A product prepared through the synthesis method is esterified on the basis of grafting, and a finally synthesized product, namely the bagasse xylan syringic acid ester-g-AM, improves the problem of low water solubility of the bagasse xylan and also expands the application field of the bagasse xylan. Meanwhile, by the introduction of active groups of acrylamide (AM) and the syringic acid, the bioactivity of the bagasse xylan is further improved.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a method for synthesizing bioactive derivative bagasse xylan syringate-g-AM. Background technique [0002] Xylan is an abundant, renewable and degradable polysaccharide polymer widely found in wood, grass, cereal and herbaceous plants. In recent years, more and more scientific researchers are interested in the application of xylan in food, medicine, biology and other fields. At the same time, researchers are committed to the development of xylan single-modified derivatives of high value-added products such as esterification derivatives, graft copolymerization derivatives, etherification derivatives, etc., but the research on xylan compound denatured derivatives just getting started. [0003] Studies have found that grafting polysaccharides with monomers containing vinyl groups can significantly improve their water solubility and biological activity, such as enhancing ...
