The invention belongs to the technology of ocean chemical engineering, in particular to a 6-amine-substituted-6-deoxidizing chitosan derivant and a preparation method thereof. As shown in the general formula I, an amino compound can be introduced at the 6 position of chitosan, so that the derivant is strong in area selectivity. By introducing toxic or non-toxic amino-compounds on the chitosan, remarkable effects for improving anti-bacteria effect of the chitosan can be achieved, and the production using process of the derivant is led to be low in toxicity and environment-friendly. The formula I is shown in the description, wherein m=0-20; and n=4-4000. |
