| 摘 要： | 以没食子酰基为功能基团,以改性纤维素为骨架合成功能高分子材料没食子酰化改性纤维素(没食子酰基-1,6-己二亚胺基-羟丙基-纤维素,CG):先将纤维素与环氧氯丙烷反应,然后依次接上己二胺桥链和三乙酰基没食子酰基,最后将没食子酰基脱去乙酰基得到目标产物。功能试验表明,1g产物能结合明胶49.5mg,并可再生使用。1g产物络合金属离子的能力:Fe3 53.4mg,Cu2 38.7mg,Hg2 46.5mg,Mn2 6.8mg,Zn2 27.9mg,Pb2 57.2mg。产物在稀酸、稀碱、稀醇和热水中具有稳定性。

| Abstract: | A new type of functional polymer material,galloyl modified-cellulose(galloyl-1,6-hexyldiimino-oxypropyl-cellulose,CG),was synthesized with phenolic acid as functional group and modified cellulose as molecular skeleton.The synthesis procedure was as follows:cellulose was first reacted with epichlorohydrin,then the hexyl diamine bridge chain and triacetyl-galloyl group were successively connected,and finally the galloyl group was deacetylated.Functional tests indicated that 1 g of CG could adsorb 49.5 mg of gelatin and be reusable after regeneration,and complex the metallic ions such as:Fe3 53.4 mg,Cu2 38.7 mg,Hg2 46.5 mg,Mn2 6.8 mg,Zn2 27.9 mg,Pb2 57.2 mg,respectively.The product CG was stable in dilute acidic,alkaline,ethanolic solutions and hot water. |
