Synthesis and Characterization of O-2-hydroxypropyltrimethyl Ammonium Chloride Chitosan |
| |
| Abstract: | O 2 hydroxypropyltrimethyl ammonium chloride chitosan was synthesized via Schiff base intermediates. By reacting benzaldehyde and chitosan, the C 2 amino group in chitosan was protected, after reaction between the chitosan Schiff bsae and 2,3 epoxypropyltrimethyl ammonium chloride, the Schiff base was removed to obtain O substituted chitosan quarternary ammonium salt, which was soluble in water and partial alcoholic solvents. Their structures were characterized by IR and NMR spectroscopy. |
