Description

Technical Field

[0001] This utility model relates to the technical field of nicotine salt synthesis apparatus, and in particular to a microwave reaction apparatus that can be used to synthesize nicotine salts. Background Technology

[0002] Nicotine salts are the product of the reaction between nicotine and acid, and are the core component of e-liquid. Compared to free nicotine, nicotine salts offer a better taste and higher absorption efficiency, significantly enhancing the user's enjoyment and satisfaction. Currently, the industrial production of nicotine salts mainly involves heating nicotine with organic acids in a solvent. However, this process suffers from problems such as long reaction times, uneven heating of the reaction solution, and low nicotine salt conversion rates. These issues significantly impact production efficiency and product quality.

[0003] Microwaves are electromagnetic waves with a frequency range of 300 MHz to 300 GHz, capable of deep heating of substances. Since the 1970s, microwave heating has gradually been applied to food processing and chemical production. In chemical synthesis, compared to traditional heating reactions, microwave reactions can directly heat the reactants both internally and externally simultaneously using microwave radiation, offering advantages such as rapid heating, strong penetration, and good uniformity, significantly increasing reaction rates and shortening reaction times. Currently, there are no reports of microwave reactors being used in nicotine salt synthesis. Summary of the Invention

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] In the description of the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] like Figure 1-4 As shown, one embodiment of this utility model is a microwave reaction device for synthesizing nicotine salts, comprising a support base 1, a housing 2, a reaction vessel 3, a stirring device 4, a microwave generator 5, and a controller 6.

[0029] The housing 2 is mounted on the upper part of the support base 1. The bottom of the housing 2 is equipped with a drive motor 201, a drive gear 202, a rotating gear 203, a turntable 204, and a gasket 205. A reaction vessel 3 is housed inside. A controller 6 is located on the outer front wall, and two microwave generators 5 are mounted on the left and right side walls respectively. The turntable 204 and the gasket 205 are made of polytetrafluoroethylene (PTFE). The shape of the gasket 205 matches the lower part of the reaction vessel 3, with the lower part of the reaction vessel 3 mounted on top of the gasket 205, and the gasket 205 mounted on top of the turntable 204. The output end of the drive motor 201 is fixedly connected to the drive gear 202. The upper part of the rotating gear 203 is fixedly connected to the lower part of the turntable 204. The rotating gear 203 can cooperate with the drive gear 202. When the drive motor 201 is turned on, the drive gear 202 drives the rotating gear 203 to rotate, which in turn drives the turntable 204, the gasket 205, and the reaction vessel 3 to rotate together.

[0030] The reaction vessel 3 is located inside the housing 2. The top of the reaction vessel 3 has an inlet 301 and a pressure relief valve 302. Inside, a temperature sensor 303, a stirring shaft 402, and a stirrer 403 are installed. The bottom has an outlet 304. The stirring device 4 includes an explosion-proof motor 401, a stirring shaft 402, and a stirrer 403. The explosion-proof motor 401 is located at the center of the upper part of the reaction vessel 3, and its bottom extends through the top of the reaction vessel 3. The output end of the bottom of the explosion-proof motor 401 is fixedly connected to the top of the stirring shaft 402, and the stirrer 403 is fixedly connected to the bottom of the stirring shaft 402. Both the stirring shaft 402 and the stirrer 403 are made of polytetrafluoroethylene (PTFE).

[0031] The controller 6 is installed on the outside of the front wall of the enclosure 2 and is electrically connected to the drive motor 201, the explosion-proof motor 401, the microwave generator 5 and the temperature sensor 303, so that the controller 6 can control the operating status of the device.

[0032] Working Principle: Controller 6 is activated, inlet 301 is opened, and reactants are added to reaction vessel 3 through the inlet. Inlet 201 is then closed. Controller 6 activates the explosion-proof motor 401, which drives the stirring shaft 402 and stirrer 403 to rotate. Controller 6 sets the reaction temperature to 60℃ and activates the drive motor 201 and microwave generator 5. Drive motor 201 drives the drive gear 202, rotating gear 203, turntable 204, gasket 205, and reaction vessel 3 to rotate together. Simultaneously, the microwave generator starts working, emitting microwaves into reaction vessel 3, heating the mixture inside and inducing a reaction. If the pressure inside the reaction vessel reaches the critical pressure of the pressure relief valve 302, the valve automatically opens to release pressure. When temperature sensor 303 detects that the reaction temperature is higher than 60℃, controller 6 reduces the power of microwave generator 5. After the reaction is complete, turn off the switches of microwave generator 5, drive motor 201, and explosion-proof motor 401, and release the nicotine salt product from the outlet 304. Open the inlet 201, add clean water to the reaction vessel 3, and clean the inside of the reaction vessel 3.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
