Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of purification devices, in particular to a tetramethylammonium acetate purification device. Background Art
[0002] Tetramethylammonium acetate is a biochemical reagent that can be used as a biomaterial or organic compound in life science-related research. It is also a raw material for the synthesis of 4-chloro-N-methylpyrimidin-2-amine.
[0003] Tetramethylammonium acetate can be synthesized using tetramethylammonium hydroxide and acetic acid, dimethyl carbonate and ammonium acetate, and other methods. In the preparation process of tetramethylammonium hydroxide and acetic acid, since tetramethylammonium hydroxide and tetramethylammonium acetate are more similar, sufficient acetic acid is added to react to produce tetramethylammonium hydroxide as much as possible. The yield of tetramethylammonium acetate produced using dimethyl carbonate and ammonium acetate is lower, and the presence of methyl carbonate in the reaction system reduces the purity of the tetramethylammonium acetate, necessitating purification. Summary of the Invention
[0004] To address the above-mentioned problems, the present invention discloses a tetramethylammonium acetate purification device, comprising a tank body, a connection port provided at the middle of the lower end of the tank body, and a heating rod disposed within the connection port. The heating rod generates heat when energized, thereby heating the material within the tank body.
[0005] An air compressor is installed on one side of the tank body. An exhaust pipe is fixedly connected to the upper end of the tank body. The other end of the exhaust pipe is fixedly connected to the input end of the air compressor. The output end of the air compressor is fixedly connected to a gas inlet pipe, and the other end of the gas inlet pipe is fixedly connected to a condenser. The air compressor vacuums the interior of the tank body, creating a low-pressure environment inside the tank body, which is conducive to the vaporization of the material inside the tank body. At the same time, the low-pressure environment eliminates the need to heat the material to a high temperature, which is beneficial to the thermal stability of the material and reduces thermal decomposition. The condenser box can collect the vaporized material for reuse after processing, and also avoids pollution caused by leakage.
[0006] Preferably, the condenser box includes a box body, within which a refrigerant chamber and a condensing chamber are disposed. The refrigerant chamber and the condensing chamber are bilaterally symmetrically arranged and arranged in an "S" shape. A delivery pipe is fixedly connected to the lower portion of the condenser box, and the gas inlet pipe and the delivery pipe are both connected to the condensing chamber. This "S" distribution increases the travel distance of the vaporized material from the gas inlet pipe into the condensing chamber and then out of the delivery pipe, thereby facilitating the liquefaction of the material.
[0007] Preferably, the upper end of the condensation box is fixedly connected to a refrigerant outlet pipe, and the lower end of the condensation box is fixedly connected to a refrigerant inlet pipe, and the refrigerant outlet pipe and the refrigerant inlet pipe are both connected to the refrigerant chamber. Refrigerant is introduced from the outside to absorb heat, so that the gasified material is liquefied.
[0008] Preferably, a plurality of heat conducting plates are provided inside the box body, and the heat conducting plates are provided across the refrigerant chamber and the condensing chamber. The heat conducting plates are provided to improve the heat conduction efficiency between the condensing chamber and the refrigerant chamber.
[0009] Preferably, a support rod is fixedly connected to the back of the box, and the other end of the support rod is fixedly connected to the side wall of the tank. The support rod is used to support and fix the condensation box.
[0010] Preferably, a plurality of support legs are fixedly connected to the lower portion of the tank body, and a material pipe is fixedly connected to the lower portion of the tank body. The support legs support and fix the tank body, and the material pipe is used to feed materials into or out of the tank body.
[0011] Preferably, the lower end of the heating rod is fixedly connected to a connecting post, which is threadedly connected to the connecting port, and a cable is extended from the lower end of the connecting post. The connecting post allows the heating rod to be removed from the tank body for easy maintenance and replacement, and the cable is used for power supply.
[0012] The beneficial effects of the present invention are as follows:
[0013] 1. An air compressor and a heating rod are provided to vaporize the material in the tank at a lower temperature to improve the purity of tetramethylammonium acetate. For example, tetramethylammonium acetate is produced from dimethyl carbonate and ammonium acetate. The boiling point of dimethyl carbonate is 90 to 91°C under standard pressure. Under the action of the air compressor, dimethyl carbonate is vaporized at a temperature below 90°C. At the same time, ammonium acetate will decompose into ammonia and acetic acid, which will eventually be vaporized, thus ultimately achieving improved purity of tetramethylammonium acetate.
[0014] 2. A condensation box is provided. The vaporized material from the inside of the tank enters the condensation box for liquefaction treatment and can be collected and processed for reuse. BRIEF DESCRIPTION OF THE DRAWINGS
