| titleOfInvention | Method for preparing chitosan-acetylsalicyclic acid(aspirin) salt compound and the chitosan-aspirin salt compound thereof |
| abstract | The present invention relates to a method for preparing a water-soluble chitosan-acetylsalicylic acid (aspirin) salt compound and a water-soluble chitosan-acetylsalicylate salt compound prepared therefrom,n n n Chitosan having a molecular weight between 1,000 g / mol and 2,000,000 g / mol and a deacetylation degree between 50% and 99% in 0.1-10% by weight aqueous solution of acetylsalicylic acid in which acetylsalicylic acid was dissolved in water at a temperature of 20-50 ° C. Adding and dissolving at 1-10% by weight to form an aqueous chitosan solution; Andn n n Aging the chitosan aqueous solution at a temperature of 0-60 ° C. for 12 hours-100 days to form a chitosan-acetylsalicylate compound; Ton n n A method for producing a water-soluble chitosan-acetylsalicylic acid (aspirin) salt compound is provided.n n n In addition, the content of chitosan to acetylsalicylic acid produced by a mixture of chitosan and acetylsalicylic acid having a molecular weight of 1,000-2,000,000 g / mol and a degree of deacetylation of 50-99% for 12 hours-100 days at a temperature of 0-60 ℃ A water-soluble chitosan-acetylsalicylate compound having a ratio of 10: 90-70: 30 weight ratio is provided.n n n The chitosan-acetylsalicylate compound of the present invention is capable of releasing a uniform amount of aspirin, which is very stable, and has the ability to bond to chitosan, protein adsorption, film formation, antibacterial and deodorant activity, and It has antipyretic and anti-inflammatory effects and can be effectively used for the protection or treatment of various skin diseases such as athlete's foot, eczema, allergy, inflammation, atopic dermatitis and skin wounds such as burns, wounds and abrasions. |
