摘要 |
A process for making modified N-acetylated chitosan comprising the steps of: a) forming an aqueous solution of chitosan in aqueous acid; b) mixing the resulting solution of step a) with an acetylating agent in a chitosan:acetylating agent sub-stoichiometric amount; and c) allowing the chitosan and acetylating agent to react for a length of time sufficient for substantial completion of the acetylation reaction.
