| titleOfInvention | Fluorescent dye intermediate using chitosan oligomer and preparation method thereof |
| abstract | The present invention relates to a fluorescent dye intermediate using a chitosan oligomer and a method for preparing the same. The chitosan oligomer is prepared by reacting a chitosan polymer in a 1-5% hydrogen peroxide solution at 50 to 100 ° C. while maintaining a pH of 10.5 to 12.5. After the preparation, cyanuric chloride is added to react the conditions at 0 to 10 ° C. and pH 7 to 9 to form a chitosan oligomer-cyanuric chloride conjugate (CO-CY), which forms 4,4′-. Chitosan oligomer-cyanuric chloride-4,4'-diaminostilben-2,2'-disulfonic acid (CO-CY- It is characterized in that to form a DAS) conjugate, by the present invention can be obtained from chitosan polymer to obtain an oligomer having a high content of pentamers or hexamers excellent in antibacterial and deodorizing properties can be bonded to the dye intermediate. |
