CAS NO.: 9012-76-4

Molecular formula: (C6H11NO4) N

Molecular weight: 161.2

Physical properties: pure chitin and chitosan is a kind of pure white or grey white translucent sheet or powdered solid, tasteless, odorless, non-toxic, pure chitosan with Pearl gloss. The relative molecular mass of organisms in chitin is 1 * 106 to 2 * 106, relative molecular mass after the extract chitin is about 3 * 105 to 7 * 105, the preparation of chitosan from chitin relative molecular quality is lower, about 2 * 105 to 5 * 105. In the manufacturing process of chitin and chitosan molecular size, generally represented by the numerical viscosity. According to the purpose of different commercial chitosan with three different viscosity, high viscosity products is 0.7 ~ 1Pa / s, medium viscosity products of 0.25 ~ 0.65 Pa s, <0.25 Pa s low viscosity products. The manufacture of fiber products to use of chitin or chitosan with high viscosity.
