磺化壳聚糖的制备及IR光谱

Synthesis of Chitosan Sulfonate and Its IR Spectrum

将片状壳聚糖溶解制成凝胶 ,冷冻分离 ,洗涤 ,DMF-苯蒸馏除水后 ,以氯磺酸 - DMF为磺化试剂 ,在适当条件磺化 ,获得水溶性良好的磺化壳聚糖 ,用红外光谱进行了结构表征。

A water-soluble chitosan sulfate was synthesized from chitosan as raw material and characterized by IR spectrum. The results indicate that the sulfonation reaction mainly occurred partially at C—6 and C—3 position.
