| Abstract: | A method for preparation of chito-oligosaccharides and peracetylated-chito-oligosaccharides was studied.The factors that influence the degradated products,such as material,temperature and time were tested via an orthogonal experiment.Eight oligosaccharides,i.e.,octaacetyl-diglucosamine,undecaacetyl-triglucosamine,tetradecaacetyl-tetraglucosamine,haptadecaacetyl-pentaglucosamine,N,N'-diacetylglucosamine,N,N',N'-triacetylglucosamine,N,N',N',N'-tetraacetylglucosamine and N,N',N',N',N'-pentaacetylglucosamine,were prepared efficiently,and their chemical structures were confirmed by IR,NMR and MS spectra. |
