| titleOfInvention | A kind of preparation method of the hydroxymethylfurfural composition of chitosan/5 |
| abstract | The present invention relates to a kind of preparation method of the hydroxymethylfurfural composition of chitosan/5, this method obtains solution A with acidic aqueous solution dissolving chitosan class material first, again pre-reaction liquid is mixed to get by solution A and containing 5 hydroxymethylfurfural solution, alkali lye is added in pre-reaction liquid and adjusts its pH, pre-reaction liquid is 4 DEG C ~ 85 DEG C in temperature, mixing speed carries out condensation reaction under the conditions of being 100 ~ 500r/min, obtain in the hydroxymethylfurfural composition of gel or cotton-shaped chitosan/5, it is freeze-dried after carrying out dialysis treatment to the hydroxymethylfurfural composition of reacted chitosan/5 with deionized water, obtain the hydroxymethylfurfural composition of dry chitosan/5.The hydroxymethylfurfural composition of the chitosan that the present invention is prepared/5 can retain more NH 2 Group, so as to retain the performances such as more excellent unique antibiotic property, biological adhesiveness. |
