【摘要】 利用过硼酸钠（NaBO₃）将壳聚糖在酸溶液中进行均相降解反应制得低分子量的水溶性壳聚糖,确定了最佳降解条件,并对降解机理、降解效率和降解产物结构进行分析。试验结果表明,这是一种有效氧化降解壳聚糖的方法,而且不会影响活性基团（—NH₂）的含量。更多还原

【Abstract】 A water - soluble low molecular chiosan was prepared by homogeneous degradation of chitosan using NaBO3 as oxidizer in acid solution. The best degrading condition was determined. The degrading mechanism, the degrading efficiency, and the structure of product were discussed. The test results showed that the method was efficient, which couldn t affect the content of active group (-NH2) .更多还原
