The acetylation method of chitosan |
| abstract |
The present invention relates to a method for acetylation of chitosan, which enables acetylated chitosan of a desired acetylation degree to be produced. The method comprises producing a crude reactant solution using chitosan or chitosan oligosaccharide produced by decomposition and deacetylation of chitin as a raw material; and passing the crude reactant solution through an inline mixer while sequentially continuously a pH-adjusting agent and acetic acid anhydride into the inline mixer, so that the crude reactant solution is subjected to acetylation reaction. |
