| titleOfInvention | Chitosan derivative and method for producing the same |
| abstract | PROBLEM TO BE SOLVED: To surely synthesize a chitosan derivative which does not largely impair the basic chemical structure of chitosan and has water solubility even if it has a high molecular weight, and the chitosan derivative having few by-products. To provide a manufacturing method that can be used. A D-glucosamine and a derivative thereof are β-glucosamine. A chitosan derivative composed of an ether bond at the 1,4 position, represented by the formula (1), wherein n1 + N2 + n3≥5, n1 / (n1 + n2 + n3) ≤0. 2, and a polyoxyalkylene group is bonded to the nitrogen atom. A polyoxyalkylene compound having an aldehyde group at one end is reacted with chitosan to form a Schiff base, which is then reduced. Embedded image |
