Description

Technical Field

[0001] This utility model relates to the field of organic compound synthesis technology, and in particular to a constant-temperature organic compound synthesis reaction apparatus. Background Technology

[0002] Organic synthesis refers to the process of using chemical methods to transform elements, simple inorganic substances, or simple organic substances into more complex organic substances. Temperature is one of the important factors affecting the rate and yield of organic reactions. Too high or too low a temperature may lead to incomplete or unsatisfactory reactions. Therefore, optimizing the temperature of organic reactions is crucial.

[0003] Currently, materials in the reaction vessel are typically heated using heating rods. Before heating the materials, a vacuum must be maintained in the reaction vessel to prevent impurities in the air from contaminating the organic compounds during synthesis. Therefore, rubber sealing rings are usually installed at the sealing points of the vessels. However, during continuous high-temperature heating of the materials, the rubber sealing rings are prone to melting due to the high temperature, affecting the sealing performance of the reaction vessel.

[0004] Therefore, it is necessary to improve the existing technology to solve the above-mentioned technical problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a constant-temperature organic compound synthesis reaction apparatus, which solves the problems mentioned in the background section.

[0007] As a further technical solution of this utility model, a sliding groove is fixedly installed in a circumferential arrangement on the inner side wall of the reaction cylinder, and a sliding block is fixedly connected in a circumferential arrangement on the outer side wall of the reaction cylinder, and the sliding block is slidably connected to the sliding groove.

[0008] As a further technical solution of this utility model, a rubber sealing ring is fixedly connected to the lower side of the outer wall of the sealing cover, and a connecting block is fixedly connected to the front end of the side wall of the housing and the sealing cover. A locking screw is inserted into both the upper and lower connecting blocks, and a locking nut is threaded to the lower end of the outer wall of the locking screw.

[0009] As a further technical solution of this utility model, an annular groove is provided inside the sealing cover and above the rubber sealing ring. A water-blocking plate is fixedly installed on the inner wall of the annular groove. An inlet and an outlet are fixedly connected to the side wall of the sealing cover and on the left and right sides of the water-blocking plate, respectively.

[0010] As a further technical solution of this utility model, a rotating handle is fixedly connected to the side wall of the sealing cover, and connecting columns are fixedly installed in a circumferential arrangement on the upper side of the outer wall of the reaction cylinder. A connecting ring is fixedly connected to the upper end of the outer wall of the connecting column, and hooks are symmetrically fixedly connected to the upper side of the outer wall of the connecting ring.

[0011] As a further technical solution of this utility model, an exhaust pipe is fixedly connected to the upper end of the outer wall of the sealing cover, and a valve is fixedly installed on the exhaust pipe.

[0012] This invention provides a constant-temperature organic compound synthesis reaction apparatus, which has the following advantages compared with the prior art:

[0013] 1. This utility model uses a reaction cylinder to hold materials. The device can be connected to an external negative pressure pumping device through an exhaust pipe to perform vacuum treatment inside the shell. The vacuum state inside the shell is maintained by closing the valve. The device heats the inside of the shell by activating the heating rod.

[0014] 2. In use, the water inlet and outlet on the sealing cover are connected to the external water system. Water is input into the annular groove through the water inlet, and the water in the annular groove is discharged from the water outlet. The water flowing in the annular groove carries away the heat around the annular groove, thereby dissipating heat from the rubber sealing ring below, preventing the rubber sealing ring from melting due to excessive temperature, thus improving the service life of the rubber sealing ring and increasing the practicality of the device.
