SDS of cas: 93-97-0. Recently I am researching about CHITOSAN; PERFORMANCE; DERIVATIVES; CELLULOSE; DEPENDENCE; COMPLEXES; AEROGELS; C-6, Saw an article supported by the National Natural Science Foundation of ChinaNational Natural Science Foundation of China (NSFC) [51373127]. Published in WILEY in HOBOKEN ,Authors: Zhang, YH; Zhang, S; Liu, J; Hao, JF; He, BJ; Bai, ZW. The CAS is 93-97-0. Through research, I have a further understanding and discovery of Benzoic anhydride
Because 6-amino-6-deoxy amylose is an important intermediate for many materials, developing a practical pathway to easily prepare it in bulk is of significance. The synthesis of 6-amino-6-deoxy amylose included three reactions. In the chlorination reaction, the crude product could be fully de-esterified under the improved conditions, and the reaction mechanism was re-understood. The azido group was reduced with sodium borohydride in which the reaction conditions were studied in detail. With the improved synthetic pathway, 6-amino-6-deoxy amylose could be easily prepared. The 6-amino-6-deoxy amylose was characterized via its benzamide derivative with(1)H NMR,H-1-C-13 HSQC NMR, and(1)H-H-1 COSY NMR, confirming the hydroxyl group at C(6)of amylose was converted to amino group with a degree of substitution of 98.2%. Additionally, the 6-amino-6-deoxy amylose was analyzed toward iodine reagent and X-ray diffraction, and the corresponding results showed that it was different from amylose in suprastructure and crystal structure.
