| titleOfInvention | Method for homogeneous preparation of carboxyl chitin with low deacetylation degree and application of carboxyl chitin |
| abstract | The invention discloses a method for homogeneous preparation of carboxyl chitin with a low deacetylation degree and an application of carboxyl chitin. Firstly, chitin is added into a mixed aqueous solution of sodium hydroxide and urea to obtain a homogeneous chitin aqueous solution, then an aqueous solution containing a carboxyl reagent is added into the homogeneous chitin aqueous solution for stirring reaction, and the carboxyl chitin with the low deacetylation degree is obtained after posttreatment. The method has the advantages of simple preparation process, uniform and controllable substitution degree of the product, high yield, and mild reaction condition, is an environmentally friendly and green technology, and is conducive to large-scale industrialized production; the chitin is basically not degraded, and a few of prepared carboxyl chitin with the low deacetylation degree has pH sensitivity and temperature sensitivity and can be used as drug carrier materials. The prepared water-soluble high-viscosity product is obtained by modifying natural raw materials, is cheap and biodegradable, has functions similar to functions of natural moisturizing conditioner hyaluronic acid, and can be widely used in cosmetics, medicines, health care, feature beautifying, textiles, food processing, environmental protection and other fields. |
