| titleOfInvention | Method for producing and purifying cycleanine |
| abstract | The invention discloses a method for producing and purifying cycleanine, which comprises the steps of carrying out primary cooling on cycleanine production reaction liquid, filtering, carrying out secondary cooling on filtrate, standing for crystallization, filtering and drying to obtain cycleanine products. The method for producing and purifying cycleanine simplifies the operation steps of post-treatment and purification of cycleanine products; hot filtration is not needed, the potential safety hazard to operators is reduced, the operation safety level of production is reduced, and the method is green and environment-friendly; the obtained cycleanine product has high purity and good quality, improves the safety of medication, and is beneficial to realizing industrialization. |
