The Preparation of O-Carboxymethyl-Chitosan and its Particles

Abstract:

The active site of chitosan is protected basing on amino reaction method of reaction between benzaldehyde and chitosan to form Schiff. The O-carboxymethyl chitosan is obtained by the method that taking chloroactic acid to hydroxyl of chitosan as modifier in alkaline conditions to form amino protection and then remove the protection in acid conditions. The O-carboxymethyl chitosan particles with particle size distribution of 15-50μm is prepared by emulsification cross- linking method.
