The preparations of amino-cellulose derivatives and their properties

以天然纤维素为原料，经三步反应制得6-氨基-6-脱氧纤维素(6-ADC)。以6-氨基-6-脱氧纤维素和6-叠氮-6-脱氧纤维素为原料，高产率地合成了6-6-(N-phenylthiocarbamoyl)amino-6-deoxycellulose(6-PTADC)和6-氨基-6-脱氧-2，3-二O-癸酰纤维素(6-ADC-23D)。在金属吸附实验中发现，6-ADC对镉离子具有良好的选择性。6-PTADC与氢氧化铜的熔融混合物的UV-Vis-NIR光谱在近红外区域有较强的吸收，而6-ADC也可以通过葡萄糖或羟基酯衍生物的开环聚合得到。该制备方法可用于区域选择性取代6-ADC衍生物的合成。

6-Amino-6-deoxycellulose (6-ADC) was prepared from native cellulose by three reaction steps. And 6-(N-phenylthiocarbamoyl)amino-6-deoxycellulose (6-PTADC) and 6-Amino-6-deoxy-2,3-di-O-decanoyl cellulose (6-ADC-23D) were synthesized in high yields from 6-ADC, and from 6-Azido-6-deoxycellulose, respectively.6-ADC and its derivatives were subject to the metal adsorption test, and the spectroscopic measurement. It was found that 6-ADC showed a good selectivity for cadmium ion in the metal adsorption test. And UV-VIS-NIR spectrum of a fused mixture of 6-PTADC and copper hydroxide had a strong absorption at near infrared religion.On the other hand, 6-ADC could be also obtained by the ring opening polymerization of the glucoseorhtoester derivative. This preparation method is useful for the synthesis of a regio-selective substituted 6-ADC derivative.
