| 英文摘要 | the degree of n-deacetylation (dd) is an important property of chitosan. in the present article the reaction of n-acetylation was applied to prepare six chitosan samples with various dds. the samples were studied by ftir and xrd to investigate their ir absorbance characteristics and crystallinity, from which the dds and crystallinity index (cri) of chitosans were also determined respectively. the influence of n-acetylation on dd and cri was also discussed, and it could be found from ftir that the n-acetylation reaction became difficult for the remaining amino group in chitosan molecule as the reaction proceeded. xrd also indicated that the crystalline zone was broken by n-acetylation gradually, and another kind of crystal form appeared instead. |
