| Abstract: | Chitosan sulfate is prepared by using shrimp/crab shell as raw material. Some factors affecting the catalytic system of polyphase esterification when we use it (chitosan sulfate) as catalyst are what we want to discuss in this essay. By making a detailed study we've found out not only the relation between the effective efficiency of the catalyst, the molecular weight of chitosan and the deacetylation degree, but also the applied sphere of the catalytic system of polyphase esterification when we use chitosan sulfate as catalyst and the main effect factors. |
