| titleOfInvention | A kind of preparation method of high-purity Lunhuan Tengning |
| abstract | The invention discloses a preparation method of high-purity cyclamenine. The present invention uses diethylenetriamine and N-benzyldiglyoxalamine as main raw materials, adds a desiccant, absorbs the generated water, promotes the generation of imine, and at the same time introduces hydrogen to rapidly reduce the imine, so as to avoid the decomposition of the imine. The response is more thorough. The method is simple in steps, low in cost, high in yield, low in equipment requirements, environmentally friendly, and suitable for industrial production. |
