Shrimp Carboxymethyl Chitosan,
Derivative Carboxymethyl Chitosan,
Derivative Chitin Chitosan
Carboxymethyl Chitosan ; CPCTS Chitosan ; Chitin Derivative ; Water Soluble Chitosan ; shrimp& crab shells material
The concentration of sodium hydroxide in isopropanol solution with sodium hydroxide added in the reaction bottle is 40%. Chitosan with a deacetylation degree of 15% ~ 45% was added to the reaction flask, and the mass ratio of chitosan to sodium hydroxide was 1:4.8. The pre-dissolved isoacetone solution of chloroacetic acid was slowly added to the reaction bottle by dropping Chemicalbook in the stirring state. After adding, the reaction was continued for 3h. The mass ratio of chitosan to chloroacetic acid is 5:1. After the reaction, add concentrated hydrochloric acid to the reactive material, adjust the pH value of the material to 6 ~ 7, filter, wash the filter cake with anhydrous ethanol for 3 times, after washing the filter cake dry below 50℃, get the crude carboxymethyl chitosan.
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.
White or yellowish,amorphous powder.It dissolves in water and its aqueous solution is transparent and stable.
