| Abstract: | The optimum technological conditions in the usual preparation method of N,O－ carboxychitosan were determined by L9(34) orthogonal design and extreme difference analysis. It was studied that the effect of deacelylation degree of materials and stirring time on the degree of substitution of carboxymethyl groups(DS) of product. The DS of product was up to 1.25 by this technology. |
