This paper describes a novel method to determine the degree of deacetylation of chitosan by IH NMR spectroscopy. Measurements were carried out at 70~ by using 2 wt% CD3COOD/D20 and 2 wt% DCI/D20 as solvents for chitosan. In the case of DCI/D20 system, effect on hydrolysis of chitosan should be take
