Description

Technical Field

[0001] The utility model relates to reaction purification equipment for the production of indole methanol. Background Art

[0002] Indolecarbinol is mainly used as an organic synthesis intermediate and a pharmaceutical intermediate. It is used to synthesize tropisetron and antiviral drugs. It needs to be stored in a sealed container in a cool, dry place. The storage place must be away from oxidants. Indolecarbinol is slightly harmful to water. Do not allow undiluted or large quantities of the product to come into contact with groundwater, waterways or sewage systems.

[0003] In the production and processing of indole methanol, an extraction and purification process is generally required to obtain indole methanol or intermediate products with less impurities. In the authorized Chinese utility model patent "Announcement No.: CN220530693U, Name: A furfural distillation and purification device", the first synchronous wheel and the vortex spring of the eccentric structure are set, so that the device can use the first synchronous wheel to intermittently contact with the second synchronous wheel, so that the stirring blade can rotate intermittently. Under the action of the vortex spring, the stirring blade can intermittently rotate forward and reverse, so that the device can ensure that the reactants are fully mixed. In the above application, the forward and reverse rotation of the stirring blade is used to improve the mixing efficiency, but whether it is forward or reverse, the stirring blade always rotates on the same horizontal plane, resulting in faster rotation of the material in the space near the stirring blade, and more difficult rotation of the material in the space not involved by the stirring blade, making it difficult to quickly mix the material evenly, that is, the stirring method of the material is single, which affects the mixing efficiency of the material. At the same time, during the reaction process, most of the material will adhere to the inner wall of the reaction device, and the material needs to be discharged before cleaning. At the same time, the adhered material is difficult to be directly washed away by water, making it difficult to clean the device. Utility Model Content
