摘　　要：壳聚糖与苯甲醛缩合反应合成西夫碱,讨论了温度、时间、物料比对接枝率的影响。通过红外光谱表征了西夫碱的结构,利用固体碳谱计算了缩合反应的接枝率。结果表明,在用正交分析法得出的最佳条件下,接枝率为86.04%。The Shiff-base was syhthesized by chitosan and benzaldehyde, discussed some factors which is influence the grafting percent, such as temperature, time and ratio of materials. The product structure was analysed By infra- red spectroscopy. The grafting percent was accurately calculated with the solid NMR. The result show that the excellent condition which was analysed By orthogonal experimental design, the grafting percent is 86.04%.
