Description

Technical Field

[0001] This utility model belongs to the technical field of gas addition equipment, specifically relating to a hydrogen addition device. Background Technology

[0002] There are different synthetic routes for the organic synthesis of diosmin and citrus flavonoids, and the methods used in these routes vary. Some of these synthetic routes require hydrogenation to achieve the hydrogenation reaction. Hydrogenation reactions (such as catalytic hydrogenation) are mainly used to reduce specific functional groups (such as double bonds, carbonyl groups, etc.) or to remove protecting groups.

[0003] In the prior art, utility model patent CN210357093U discloses a hydrogenation reactor, including a cylindrical body, a stirring device, a power unit, a sampling port, a condensate inlet, a hydrogen outlet, an ethylene glycol outlet group, and a material outlet. The end of the stirring device is connected to the power unit, and the stirring device is located inside the cylindrical body. The sampling port, condensate inlet, and hydrogen outlet are located at the upper part of the cylindrical body, the ethylene glycol outlet group is located at the lower part of the cylindrical body, and the material outlet is located at the bottom of the cylindrical body. The hydrogenation reactor provided by this solution has a simple structure, and the addition of a stirring device to the cylindrical body allows for simultaneous stirring, resulting in better reaction performance.

[0004] The hydrogenation reactor described in the aforementioned patent mainly features a stirring device to improve reaction efficiency, but it lacks a hydrogen supply mechanism. In the organic synthesis of diosmin and citrus flavonoids, the removal of protecting groups requires the addition of hydrogen gas to the high-pressure reactor to achieve a pressurized reaction. However, due to the flammability and explosiveness of hydrogen, pumping hydrogen using a gas pump presents numerous instabilities and risks of accidents. Therefore, it is not feasible to directly pump hydrogen into the high-pressure reactor. Consequently, there is an urgent need for a hydrogenation device that can supply hydrogen to a high-pressure reactor. Utility Model Content
