Synthesis,Characterization, and Antibacterial Activity of Quaternized of N-aromatic Chitosan Derivatives Han Yongping1,Lin Qiang2 1Bio-chemical engineering college of beijing union university 100023, china 2Bio-chemical engineering college of beijing union university 100023, china 1hypyyt@163.com,2liqiang@buu.edu.cn Keywords: Chitosan, Antibacterial activity, Quaternized N-aromatic chitosan derivatives Abstract.The quaternized of N-aryl chitosan (CTS) derivatives containing different aromatic moieties were synthesized by two steps, N-aromatic Schiff and the quaternization.
The effect of the amino group’s charge density and phenol hydroxyl of quaternized N- aromatic CTS derivatives on antimicrobial activity was investigated. Ⅱ.Exprtimental 2.1 Materials CTS were purchased from Qingdao Haidebei Bioengineering Co.
Therefore, it can be supposed that the positive charge density of CTS is a key factor to the antibacterial activity of CTS and its derivatives.
