[0001] The utility model relates to the field of dehydrogenation reaction, in particular to a dehydrogenation reaction device for piperidine derivatives. Background Art

[0002] Dehydrogenation is an important type of reaction that is widely present in chemical reactions. In this type of reaction, organic compounds lose one or more hydrogen atoms to generate corresponding dehydrogenation products. Dehydrogenation reactions have important application value in organic synthesis, energy conversion, and environmental protection. During the preparation and synthesis of piperidine derivatives, biological dehydrogenation reactions are required.

[0003] According to the disclosed patent 202120870571.6, a dehydrogenation reaction device for producing sodium hypochlorite includes a reactor and a buffer tank. A coil containing air holes is arranged at the bottom of the reactor. A chlorine pipe and an air blowing pipe are connected to the outside of the coil. The upper part of the reactor is also provided with a liquid inlet pipe extending to the top of the coil inside the reactor. The buffer tank is connected to the top of the reactor through an exhaust pipe. The connection part of the exhaust pipe and the buffer tank has a bell-shaped connection. An exhaust pipe connected to the outside of the room is also connected to the buffer tank. The connection part of the buffer tank and the exhaust pipe has a bell-shaped connection. The utility model solves the problems of reaction stirring, electrolyte dehydrogenation, chlorine absorption and backflow, reaction safety and other issues in the reactor by blowing compressed air or nitrogen after the coil in the reactor is connected to the air blowing pipe, greatly shortens the dehydrogenation process of the chlorine production process, and saves production space. In the process of realizing the utility model, the inventor finds that at least the following problems in the prior art have not been solved. Although the problems of reaction stirring, electrolyte dehydrogenation, chlorine absorption and backflow, reaction safety and other issues in the reactor are solved by blowing compressed air or nitrogen after the coil in the reactor is connected to the air blowing pipe, greatly shortens the dehydrogenation process of the chlorine production process, and saves production space, in the process of using the conventional piperidine derivative dehydrogenation reaction device, more raw materials will adhere to the surface of the stirring structure during the dehydrogenation reaction of the raw materials. The existing general cleaning method for the stirring structure is to remove the stirring structure and rinse and clean the stirring structure. This cleaning method will waste a lot of time. For this reason, it is necessary to design a new technical solution to solve it. Utility Model Content

It provides a device for dehydrogenation of piperidine derivatives to solve the technical problem that in the conventional device for dehydrogenation of piperidine derivatives, a large amount of raw materials will adhere to the surface of the stirring structure during the dehydrogenation reaction of the raw materials. The conventional cleaning method of the stirring structure is to dismantle the stirring structure and rinse and clean the stirring structure, which wastes a lot of time.
