Chitosan Schiff Base

2-mercaptobenzothiazol [1] was reacted with anhydrous carbonate sodium and ClCH2COOH in distilled water to produce a compound [2]. Compound [3] was synthesized by reaction compound [2] with SOCl2 in benzene. O,N-chitosan derivative [4] had synthesized by reacted chitosan with compound [3] in trichloromethane and pyridine. O-chitosan derivative synthesized according to the method of Fischer and Speier from the reaction of chitosan with compound [2] in distilled water in acidic media to produce compound [5]. O-(carboxyl) chitosan Schiff base derivatives [6-9] had synthesized by reaction O-(carboxyl) chitosan [5] with aromatic aldehydes (syringaldehyde, 3-methoxy,4-hydroxybenzeldehyde, 4-nitrobenzeldehyde, 4-bromobenzeldehyde). The structure of produced compounds has been characterized through their spectral and analytical data, as in fourier transform infrared (FTIR) spectra,1H-NMR, UV-vis spectroscopy, elemental analysis (CHNS), scanning electron microscope (SEM), differential scanning calorimetry (DSC), and thermo gravimetry analysis (TGA). Finally, study the antibacterial activity of some prepared polymers.
