| titleOfInvention | A kind of technology of utilizing biomass to prepare D-glucosamine hydrochloride |
| abstract | The invention relates to the technical field of glucosamine preparation, in particular to a process for preparing D-glucosamine hydrochloride from biomass, comprising: (1) washing shrimp shells and/or crab shells, drying them, and then adding hydrochloric acid Decalcification is carried out, excess sodium carbonate is added after completion, and then the reaction is heated, and after completion, the shrimp shells and/or crab shells are washed and dried to obtain carapaces. (2) reacting chitin, ammonium chloride, volatile organic alcohol and water under high temperature and high pressure to obtain a hydrolyzate. (3) the hydrolyzed solution obtained in step (2) is mixed with activated carbon, the decolorized hydrolyzed solution is mixed with excessive sodium hydroxide, then heating reaction, and the pH of the reaction solution is adjusted with hydrochloric acid after completion to obtain glucosamine hydrochloride solution. (4) Dry the glucosamine hydrochloride solution to obtain. The process effectively reduces the problems caused by the need to use a large amount of strong acid and strong alkali in the traditional process of preparing D-glucosamine by using biomass such as shrimp shells and crab shells. |
