Description

Technical Field

[0001] This utility model relates to the field of chemical experimental equipment technology, and in particular to a photoreaction device with magnetic stirring. Background Technology

[0002] Magnetic stirrers are indispensable experimental tools in chemical reactions. By using a magnetic field to drive the stir bar to rotate, they effectively mix reactants, ensuring sufficient contact between them and thus improving reaction efficiency and yield. At the same time, magnetic stirrers also possess precise temperature control capabilities, maintaining the specific temperature conditions required for the reaction, which helps in the selectivity and rate control of the reaction.

[0003] Photochemical reactions, also known as photochemical processes, refer to chemical reactions caused by the action of light, specifically chemical reactions that occur when substances absorb light energy under the irradiation of visible, infrared, or ultraviolet light. Compared to other chemical reactions, photochemical reactions are characterized by high selectivity, cost-effectiveness, mild reaction conditions, and ease of control, making them very important in the field of chemistry. As a key piece of equipment in photochemical production, the performance of the photochemical reactor plays a crucial role in the application of the photochemical reaction process.

[0004] Compared to other fields, photochemical research started late and is relatively shallow. High-end, sophisticated photochemical research instruments and equipment are scarce and expensive, hindering widespread adoption. Previous photochemical reactors had the following shortcomings: first, they were primarily designed for single experiments, unable to conduct multiple sets of experiments; second, photochemical reactions easily lead to increased ambient temperature, potentially transforming the reaction into a thermochemical reaction and affecting experimental results; and third, solutions or suspensions could only be homogenized through aeration, resulting in high costs and complex systems.

[0005] In summary, there is an urgent need for a photoreaction device with magnetic stirring to solve the problems existing in the related technologies. Utility Model Content
