Study on the preparation of water-soluble chitosan by deacetylation of ultrafine chitin
Water-soluble chitosan was prepared form ultrafine chitin by deacetylating in 45% NaOH solution while the reaction temperature is not more than 80℃, the degree of deacetylation was controlled around 0.5. The XRD showed that the the water-soluble chitosan is amorphous.
