[0002] Isobornyl methacrylate is a colorless or light yellow liquid with a specific chemical structure and properties. It is a low-toxic, high-boiling-point, low-viscosity compound with good compatibility with a variety of synthetic resins and natural oils. In the production of isobornyl methacrylate, camphene and methacrylic acid are usually used as raw materials, and it is synthesized by olefin electrophilic addition reaction under zirconium-containing catalysts.

[0003] After extensive searching, the publication number CN219765325U discloses a reaction device for preparing isobornyl methacrylate, which belongs to the field of isobornyl methacrylate preparation. The device can enable a bracket with a stuffing tube inserted therein to be lifted to a working platform together with a stirring mechanism and a kettle cover, so that the stuffing tube can be taken out of and put into the bracket without using an iron hook, thereby not only improving the safety of the stuffing tube taking and putting operation, but also making the replacement operation of the catalyst for isobornyl methacrylate production easier and the replacement efficiency can be improved.

[0004] Since the chemical reaction for synthesizing isobornyl methacrylate usually needs to be carried out within a certain temperature range to ensure the smooth progress of the reaction, when the temperature is too low, the reaction rate may be slow, while when the temperature is too high, side reactions may occur, affecting the purity of the product.

Therefore, a low-temperature controlled reactor for the production of isobornyl methacrylate is proposed to solve the above problems. Utility Model Content

The safety control logic equipped in the equipment can prevent the reaction temperature from being too low or too high, thereby avoiding affecting the reaction rate and the quality of the product. By maintaining the optimal reaction temperature, the reaction rate can be accelerated, the yield and quality of the product can be improved, thereby improving the overall production efficiency. The refrigeration circulation pump 21 and the heating circulation pump 31 are both designed to be energy-efficient, thereby reducing energy consumption and reducing production costs, and achieving the effect of precise control of the temperature during the reaction.
