| titleOfInvention | A kind of preparation method of 6-aminocaprolc acid |
| abstract | A kind of preparation method of 6-aminocaprolc acid dissolves polyethylene glycol in water, and polyvinyl alcohol is added, amidase is added after cooling and mixes, and note forms disc-shaped structure in the plane, moves into 30 DEG C of constant incubators dryings, moves into Na 2 SO 4 Solution is filtered dry, and is washed 2 times, and phosphate buffer solution is added, obtains immobilized enzyme；Caprolactam, ammonium formate and phosphate buffer are sequentially added in a reservoir, concentrated ammonia liquor is added dropwise into container, immobilized enzyme is then added, and is placed on 30 DEG C of stirred in water bath reaction, obtain reaction solution；Active carbon decoloring is added, again through rectification under vacuum after filtering, natural cooling crystallization, infra-red drying obtains purification 6-aminocaprolc acid.The present invention is using caprolactam as raw material, using amidase as hydrolyst, reaction condition is mild, high catalytic efficiency, yield is up to 90%, operating procedure is simple, does not need ion exchange resin and is neutralized, reduces production cost, synthetic technology is easy to industrialization, is the development trend of chemicals synthesis from now on. |
