| titleOfInvention | (2-hydroxyl-3-dehydrogenation fir oxygen base) propyl group chitooligosaccharide-and preparation method thereof |
| abstract | Prepare the technique of three main process through comprising the preparation of dehydrogenation fir base glycidyl ether, water-soluble chitosan-oligosaccharide preparation and (2-hydroxyl-3-dehydrogenation fir oxygen base) propyl group chitooligosaccharide-, obtaining a kind of is nonionogenic tenside (2-hydroxyl-3-dehydrogenation fir oxygen base) the propyl group chitooligosaccharide-of raw material based on rosin and chitosan.Its process is as follows: dehydroabietinol and epoxy chloropropane obtain after dehydrogenation fir base glycidyl ether through addition and ring-closure reaction, react through the chitooligosaccharide-that the molecular weight that oxidative degradation generates is 500 ~ 50000 with chitosan, the final average graft(ing) degree generating glucosamine unit reaches nonionogenic tenside (2-hydroxyl-3-dehydrogenation fir oxygen base) the propyl group chitooligosaccharide-of 5 ~ 300% again. |
