Themain contents of this dissertation are as follows:(1) The quality analytiedal results of chitosan are as follows: water for 15.205%;degree of deacetylation 92.671%; the weight average relative molecular weight ofchitosan 195900; the viscosity average relative molecular weight of chitosan 194100;and the decomposing temperature 298℃. The infrared ray IR spectra of chitosanshows that the feature-absorbing band of chitosan amido was 1601cm~(-1), that ofβ-indican bond was 986cm~(-1). The results of the X-ray diffraction of chitosan indicatesthat its degree of deacetylation and degree of crystal are both big.
