Spectroscopic Characterization and Preparation of LMWSC with Free-Amine Group by Novel Method |
초록 |
To obtain Low molecular water-soluble chitosan(LMWSC) with various molecular weights, the crude COS was separated according to its molecular weight by using ultrafiltration technique. LMWSC with a free amine group was prepared by the movel salts-removal method described. Absolute molecular weights(Mw),and molecular weight distribution of COS were determined by gel permeation chromatograph(GPC). Degree of deacetylation of LMWSC was determined by 1H-NMR. In the Fourier transform infrared spectroscopic, 1H-NMR and 13C-NMR spectra the absorption band by carboxyl group derived form lactic acid disappeared than that of COS. |
