Technical Field

[0001] The utility model relates to the technical field of diisopropylbenzene peroxide production, in particular to a reaction kettle for producing di-tert-butyl diisopropylbenzene peroxide. Background Art

[0002] Diisopropyl ditert-butyl peroxide (DITBP) is an important organic peroxide with broad application prospects in organic synthesis, plastic and rubber crosslinking, and chemical foaming. The synthesis of DITBP is typically carried out in a reactor. According to the production process, the raw materials are added to the reactor for a chemical reaction. Diisopropyl ditert-butyl peroxide is irritating and toxic, requiring careful protection and sealing during the synthesis process. However, the sealing cap must be opened when adding the raw materials, allowing harmful substances to escape and pollute the production environment.

[0003] Chinese Utility Model Authorization Announcement No. CN217189518U discloses a reaction device for the production of di-tert-butylisopropylbenzene hydroperoxide, comprising a reaction chamber, the bottom wall of which is fixedly mounted with four support columns, the four support columns being evenly distributed in a circular pattern, and a discharge pipe embedded in the curved side wall of the reaction chamber, which passes through the outer wall of the reaction chamber and is interconnected with the interior of the reaction chamber. Once the sealing plate leaves the interior of the sealing ring, the raw materials in the feed pipe flow into the interior of the reaction chamber through the discharge port and the inclined surface at the top of the sealing plate. However, using this device, it is difficult to accurately control the feed amount, and the material in the feed pipe needs to be replenished after each production, which is time-consuming and labor-intensive.
