| titleOfInvention | A kind of preparation method of high purity N-acetyl-D-aminoglucose |
| abstract | A kind of preparation method of high purity N-acetyl-D-aminoglucose, is related to monosaccharide.There is provided easy to operate, lower production costs, relatively inexpensive environmental protection a kind of high purity N-acetyl-D-aminoglucose preparation method.The following steps are included: 1) carry out degradation reaction to chitin with degradation agent sulfuric acid using chitin as raw material；2) filtering removes unreacted chitin, then removes unreacted sulfuric acid with embrane method；3) calcium hydroxide solid is added in the solution after embrane method removes unreacted sulfuric acid, adjusts pH value to 5.5~7.0；4) precipitating of precipitation is filtered to remove, filtered solution utilizes active carbon decoloring；5) dehydrated alcohol is added in the solution after decolourizing, until precipitating is no longer precipitated；6) precipitating is collected by filtration, is precipitated with water dissolution, adds after solid is precipitated in dehydrated alcohol and collects solid and drying to get product 2-acetylamino-2-deoxy-D-glucose powder is arrived.Product purity can be greater than 98%. |
