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.

以天然纤维素为原料，经三个反应步骤制备了6-氨基-6-脱氧纤维素（6-ADC）。6-（n -苯基硫代氨基甲氧基）氨基-6-脱氧纤维素（6- ptadc）和6-氨基-6-脱氧-2,3-二- o-癸烷基纤维素（6- adc - 23d）分别以6- adc和6-叠氮基-6-脱氧纤维素为原料合成了高收率纤维素。对6-ADC及其衍生物进行了金属吸附试验和光谱测定。在金属吸附实验中发现，6-ADC对镉离子有很好的选择性。6-PTADC与氢氧化铜熔合后的紫外-可见-近红外光谱在近红外波段有较强的吸收。另一方面，也可以通过开环聚合的方法得到6-ADC。该制备方法可用于区域选择性取代6-ADC衍生物的合成。
