Study on Preparation of Chitosan with Microwave New Technology

JU Hong-fang (Dept.of Chemistry,Changshu Institute of Technology,Changshu 215500,China)  
On the basis of the preparative mechanism and operating method of chitin,using microwave radiation technology,two kinds of crab crust are treaded.And the chitosan is prepared by chitin deacetylation.By the grope of the experiment conditions,I find the convenient preparative condition and it has a good effect.The experiments show that the deacetylation once in twenty minutes is 86.1%.Compared with the traditional method,it has some advantages such as shortening reaction time and lowering energy consumption,etc.
