| 摘 要： | 在甲磺酸体系中,将具有较好紫外吸收性能的3,4,5—三甲氧基苯甲酸分子键接到甲壳素的分子链上,制得了3,4,5—三甲氧基苯甲酰甲壳素。采用红外光谱、^1H-NMR、广角X—射线衍射、紫外光谱等表征方法对改性产物进行了结构表征。通过对改性产物的紫外光谱表征发现产物具有一定的吸收紫外线能力。产物在有机溶剂中有一定的溶解性能。

| Abstract: | 3 ,4,5-trimethoxy benzozoie acid, which has excellent UV absorbance performance, is reacted onto the chain of the natural polymer chitin, in methylsulfonic acid system. The prepared 3,4,5-lrimethoxy benzoylate chitin is characterized with FT-IK, 'H-NMR, X-ray and UV. It can be confirmed from the UV absorbent spectrum that the product has certain ultraviolet absorption. The product can be dissolved in some of organic solvents. |
