Carboxymethyl chitosan is a kind of advanced derivative of natural marine biological chitosan.It is a kind of amphoterous polyelectrolyte with good water solubility,film information,moisture and water retention,antibacterial and strong chelation.At the same time,it has biocompatibility,biodegradability,hemostasis and cullus function.It has no cytotoxicity and biological safety,and can be used for medical dressing.It has important applications in medicine,health care products,cosmetics,fresh preservation,environmental protection,chemical industry and other fields.Its stable properties,antibacterial and anti-infection,lipid-lowring and arteriosclerosis prevention and other pharmacological effects are destined to play a greater role in the future of human life.
Preparation of carboxylated chitosan:
Chitosan macromolecular chain contains both amino and hydroxyl groups. Carboxylation of amino or hydroxyl groups can be carried out on their macromolecular chains by using their reactivity. There are usually three types of reaction products. 0-carboxylated chitosan: 6-0-carboxymethyl chitosan could be synthesized under alkaline conditions by controlling reaction conditions. (2) N-carboxylated chitosan: one method is that chitosan reacts with oxalic acid, levulinic acid and other groups containing carbonyl groups to obtain schiff base, and then it is reduced with sodium borohydride. Another method is to react chitosan directly with anhydride to obtain the corresponding carboxylation products.
White or yellowish,amorphous powder.It dissolves in water and its aqueous solution is transparent and stable.
