Synthesis of chitosan benzoates derivatives |
| 초록 |
Chitosan (poly-β-(1→4)-D-glucosamine) is an amino-polysaccharide obtained by deacetylation of chitin. Chitosan is the second most abundant natural polymer, being second only to cellulose, and has characteristics cell affinity, antimicrobial activity and wound healing. Phosphoryl mixed anhydride system was applied for the preparation of chitin benzoic acid esters. The products were characterized by 1D1H-NMRand FT-IR spectroscopy. The inclusion of benzoic acid into the resulting product was confirmed from 1H-NMR and FT-IR. The solubility of the products was tested in various organic solvents. Highest solubility was obtained when the molar ratio of trifluoroacetic anhydride, benzoic acid and phosphoric acid to chitosan was 8:4:1:1 respectively. |
