Synthesis of 6-Deoxy-6-Amino Chitosan and applications thereof
Chitin and chitosan play an important role in the context of a biorefinery, where waste is converted into useful products. The introduction of an amine onto chitosan at the C-6 position has led to the synthesis of a highly water soluble chitosan derivative, 6-deoxy-6-amino chitosan. However, all …
