| titleOfInvention | Process of preparing D-glucosamine hydrochlorlde |
| abstract | The present invention relates to a method for preparing D-Gulucosamine (2-amino-2-deoxy-β-D-glucopyranose, glucosamine), which is a monomer constituting the polymer chitosan, and a hydrochloric acid having a concentration of 25 to 33% with respect to 10 g of chitin. A decomposition step of diluting the reaction solution with water, removing impurities using activated carbon, and distilling under reduced pressure after addition of 400 g of the decomposition reaction; Refining and recrystallizing the glucosamine thus prepared using an ion exchange resin column or a mixture of 3-10 times the organic solvent and water compared to glucosamine; Drying using a lyophilizer. The method for producing glucosamine according to the present invention suppresses the ring-opening reaction of glucosamine that occurs as a side reaction by using chitin as a starting material and using hydrochloric acid at an appropriate concentration, instead of using chitosan or concentrated hydrochloric acid used in conventional methods. There is an advantage of preparing glucosamine in high yield. |
