Synthesis of new Bio polymer Chitosan Double Schiff Basederivatives with Salicylaldoxime and 3-Chloro Aniline

Abstract

The Bio-composite (CS-3CA) material chitosan, salicylaldoxime and, 3-chloro aniline was synthesized at a temperature of 45°C. The functional groups were identified by FT-IR analysis. 3398cm- 1 band with (N-H) Stretching of imine in intermolecular bonding,3009cm- 1 (C-H) in vibrational bonding of Chitosan and, 1248cm- 1 (C-O-C) linkage of chitosan. The structure of this compound was confirmed by 1H NMR and 13C NMR spectroscopy analysis. The solution 1H-NMR (H-2 in 8.583 and H-6 in 4.881) and 13C-NMR (C-3 C=N-OH and C-6 C=N) is a confirmed structure of the Bio-composite. The purity of the bio-composite is 93% conformed to HPLC Analysis. The thermodynamical parameters Entropy = 2.431JK-1mol-1, Thermal stability = 160°C were calculated by TG/DSC. Chitosan derivatives will have a large impact show potential in biomedicine for the development of drugs in future.
