AI Technical Summary
Existing reaction apparatus for the preparation of dextromethorphan has poor mixing effect, resulting in some raw materials failing to react fully in the discharge structure.
The system employs an induced draft fan and a gas diversion assembly in conjunction with a stirring paddle. The rotation of the stirring paddle mixes the raw materials and generates gas. The gas is discharged through the gas diversion assembly, forming bubbles that enhance the fluidity of the solution and ensure that the raw materials react fully. In the discharge pipe, the gas flows upward to prevent unreacted raw materials from remaining.
It improves the mixing effect of dextromethorphan raw materials during the reaction process, ensuring that all raw materials react fully in the reactor, avoiding unreacted raw materials in the discharge pipe, and improving reaction efficiency.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of dessonide preparation technology, specifically to a reaction apparatus for the preparation of dessonide. Background Technology
[0002] Desonide is a corticosteroid with strong anti-inflammatory effects. Due to its higher ratio of local to systemic effects compared to other drugs in its class, it is more suitable for local use. It is a first-line drug for treating asthma by inhalation and for treating allergic reactions by nasal spray. Desonide is prepared by adding 16α-hydroxyprednisolone, acetone, and methyl butyl sulfonate imidazole hydrogen sulfate acidic ionic liquid to a reaction vessel and reacting at a temperature between 10°C and 100°C.
[0003] A search revealed that patent publication number CN221413090U discloses a reaction vessel that can effectively increase the effective volume of the reaction vessel and ensure the stirring of raw materials inside the reaction vessel. It includes a reaction tank body, an inlet and an outlet on the reaction tank body, a stirring device on the reaction tank body, and a coil on the outside of the reaction tank body, the coil including a water inlet and a water outlet.
[0004] In practical use, existing dextromethorphan preparation reaction devices generally use a stirring rod to mix and stir the dextromethorphan raw materials to enable the dextromethorphan raw materials to react. However, the above method does not achieve the desired mixing and reaction effect of the dextromethorphan raw materials, and it is easy for the dextromethorphan raw materials in the discharge structure to not undergo effective reaction. Therefore, a new dextromethorphan preparation reaction device is designed. Utility Model Content

[0014] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects:
[0015] In this invention, through the coordinated arrangement of a series of structures such as an induced draft fan and a gas diversion component, when the desonide manufacturing raw materials are mixed and reacted inside the reactor, the starting of the geared motor drives the stirring paddle on the outer wall of the rotating shaft to rotate. When the stirring paddle rotates, it stirs and mixes the desonide manufacturing raw materials inside the reactor. During the mixing and reaction of the desonide manufacturing raw materials, a certain amount of gas is generated. The starting of the induced draft fan draws in the gas inside the reactor and transports the gas to the gas diversion component. The gas in the gas diversion component is discharged from the third exhaust pipe on the first branch pipe and the second branch pipe. When the gas is discharged from the third exhaust pipe, it forms bubbles and flows upward in the solution inside the reactor, increasing the fluidity of the solution. This effectively improves the mixing effect of the desonide raw materials during the reaction process, allowing the desonide raw materials to react fully.
[0016] In this invention, through the coordinated arrangement of a series of structures such as the second branch pipe, when the gas is discharged from the third exhaust pipe on the second branch pipe, the gas will flow upward in the discharge pipe, increasing the fluidity of the solution in the discharge pipe, thereby avoiding the situation where the dextromethorphan raw material in the discharge pipe does not react sufficiently.
