| 摘 要： | 以2,4-二羟基二苯甲酮(UV-O)与氯乙酰氯为原料合成了中间体2-羟基-4-氯乙酸酯基二苯甲酮,然后使其与羧甲基壳聚精反应,合成了一系列含有二苯甲酮结构的羧甲基壳聚糖基紫外线吸收剂(CMC-g-HCBP).采用IR,UV,XRD,1HNMR等对产物进行了结构表征.测定结果表明,接枝产物在240～400 nm内均有较强的紫外吸收,并在332 nm处有最大紫外吸收;产物有较好的光稳定性.

| Abstract: | An intermediate,2-hydroxy-4-chloroacetate-benzophenone(HCBP) was synthesized by 2,4-dihydroxy-benzophenone(UV-0) and chloroacetyl chloride as starting materials.Then a series of carboxymethyl chitosan based water soluble ultraviolet absorbers(CMC-g-HCBP) were synthesized by grafting reaction of HCBP on carboxymethyl chitosan in isopropanol with the presence of sodium hydroxide.The structures of the intermediate(HCBP) and grafted products(CMC-g-HCBP) were characterized by IR,UV,XRD and 1HNMR.The results of u... |
