Chitosan CAS:9012-76-4 Product introduction
Product name: Chitosan
Appearance:It is a white or off-white translucent flaky solid with a slight pearl luster. Odorless, non-toxic and easily degradable, it is a rare natural cationic polyelectrolyte.
Chitosan Chemical Properties:
Chitosan can be obtained by deacetylating chitin. Under the conditions of 100 °C and 40% NaOH, when chitin is acted on, a deacetylation reaction occurs to obtain chitosan. This is a white or off-white translucent flaky solid that is insoluble in water and alkalis, but soluble in most dilute acids, including formic acid, acetic acid and salt Chemicalbook acid. The molecular structure of chitosan is similar to that of cellulose, the only difference is that an amino group (-NH2) is attached to the C2 position. Therefore, it has an affinity for the fibers in the paper, and develops ionic bonds and strong hydrogen bonds. Moreover, chitosan has good film-forming properties, which is beneficial to improve the surface strength of paper, so it has become one of the reinforcing agents of special paper.
