| titleOfInvention | A kind of N- thiosemicarbazides-O- quaternary ammonium salt chitosan oligosaccharide and preparation method and application |
| abstract | The invention discloses a kind of N- thiosemicarbazides-O- quaternary ammonium salt chitosan oligosaccharide and preparation method and application.Its structural formula are as follows: Preparation method is react with the amino on chitosan oligosaccharide using formaldehyde obtaining N- methylene chitosan oligosaccharide, then using C in 3- chloro-2-hydroxypropyl-trimethyl ammonium chloride and the N- methylene chitosan oligosaccharide 6 Hydroxyl on position carries out reaction and obtains N- methylene-O- quaternary ammonium salt chitosan oligosaccharide, finally carries out addition reaction using the carbon-to-nitrogen double bon of thiosemicarbazides and the N- methylene-O- quaternary ammonium salt chitosan oligosaccharide and obtains N- thiosemicarbazides-O- quaternary ammonium salt chitosan oligosaccharide.It is poor, easy to be dissolved the problem of corroding and usable in acid, neutral, alkaline aqueous solution that the present invention not only solves chitosan oligosaccharide, chitosan derivatives adsorptivity.Meanwhile its bacteriostasis property is improved, there is good effect in the absorption of metal ion and inhibition bacterium. |
