The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0045] like Figure 1-4 As shown, the present application relates to an electrochemical continuous flow reactor and a reaction system. The electrochemical continuous flow reactor comprises: a first frame 10; the first frame 10 refers to the first electrolytic cell frame, which can achieve good fixing and supporting effects; at the same time, it can also cooperate with other components to achieve multiple functional effects. Of course, the first frame 10 can also be understood as a base or a pedestal. Preferably, the shape of the first frame 10 is square; it can provide a guarantee for the subsequent required slot shape. The main body of the electrolytic cell frame is made of corrosion-resistant polytetrafluoroethylene material, which is suitable for a variety of chemical experiments.

[0046] The first conductive component 20 is embedded in one side of the first frame 10; by embedding the first conductive component 20 in one side of the first frame 10, a good assembly effect can be achieved; at the same time, a good conductive effect can also be achieved, thereby achieving the effect of stably supplying external power to the internal components of the reactor.

[0047] The reaction plate 30 is arranged adjacent to the first frame body 10 on the side close to the first conductive component 20; by providing the reaction plate 30, the effect of providing a liquid reaction environment can be achieved; at the same time, by arranging it adjacent to the first frame body 10, a good assembly effect can be achieved, and at the same time, a good fixing effect of the first conductive component 20 can be achieved.

[0048] The second conductive component 40 is embedded in the reaction plate 30 on a side away from the first conductive component 20. By embedding the first conductive component 20 on one side of the reaction plate 30, a good assembly effect can be achieved. At the same time, a good conductive effect can also be achieved, thereby achieving the effect of stably supplying external power to the internal components of the reactor.

[0049] The second frame 50 is arranged adjacent to the reaction plate 30 on the side close to the second conductive component 40; by providing the second frame 50, a good fixing and assembly effect with the reaction plate 30 and the first frame 10 can be achieved, thereby forming an effect of a reactor frame assembly; at the same time, a good fixing effect can also be achieved for the devices assembled inside the assembly.

[0050] The first electrode sheet 60 is arranged between the first conductive component 20 and the reaction plate 30, and is electrically connected to the first conductive component 20; by fixing the first electrode sheet 60 between the first conductive component 20 and the reaction plate 30 and setting them against each other, a stable assembly effect can be achieved. At the same time, by electrically connecting the first electrode sheet 60 to the first conductive component 20, a stable operation effect of the first electrode sheet 60 can be achieved.

[0051] The second electrode sheet 70 is arranged between the reaction plate 30 and the second conductive component 40, and is electrically connected to the second conductive component 40; by fixing the second electrode sheet 70 between the reaction plate 30 and the second conductive component 40 and arranging them against each other, a stable assembly effect can be achieved. At the same time, by electrically connecting the second electrode sheet 70 to the second conductive component 40, a stable operation effect of the second electrode sheet 70 can be achieved.

[0052] Of course, the first electrode sheet 60 and the second electrode sheet 70 are both thin sheets made of conductive materials, the surfaces of which can be in direct contact with the electrolyte or electrode reactants to catalyze electrochemical reactions and transfer electrons.

[0053] In this application, the electrode sheets can be replaced at will, and the required electrode sheets can be flexibly selected. The electrode materials and electrolytic cells of different sizes can be freely selected to meet various synthesis needs.

[0054] Preferably, the first motor sheet, the second electrode sheet 70, the groove, etc. are all arranged in a circular shape to increase the flow volume and the electrode contact area.

[0055] The first electrode sheet 60 and the second electrode sheet 70 cause a corresponding oxidation-reduction reaction to occur in the liquid to be reacted flowing through the reaction plate 30 .

[0056] Specifically, the two electrode sheets are electrically connected to the positive and negative poles of the external power supply through the first conductive component 20 and the second conductive component 40, respectively. When the liquid to be reacted is pumped into the electrolytic cell through the inlet and outlet of the electrolytic cell, the liquid to be reacted will gain or lose electrons from the two electrode sheets when flowing through the flow channel 303 in the reaction plate 30, thereby causing a corresponding redox reaction. The use of a continuous flow electrochemical microchannel reactor greatly reduces the flow cell spacing between the cathode and anode electrodes, greatly accelerates the rate of the cathode and anode two-stage redox reaction, improves the efficiency of the electrochemical reaction, and can even achieve a reaction without an electrolyte.

[0057] The present application can solve the problems that the current commercial flow electrolytic cells are relatively expensive; the electrode materials and the size of the electrolytic cells are fixed and cannot meet the needs of different syntheses; the operation steps are complicated, the power supply, electrolytic cell and peristaltic pump cannot be integrated into one, and additional configuration is required; the electrode spacing and flow volume of the flow electrolytic cell cannot be adjusted, and it cannot adapt to a variety of chemical reaction systems.

[0058] The present application can reduce the cost of the instrument and make it a device that most electrochemists have; integrate different functions into one to achieve a highly integrated instrument and convenient operation; configure electrolytic cells with different electrode spacings and flow volumes to flexibly adapt to a variety of organic electrosynthesis reactions.

[0059] From the above description, it can be seen that the present application achieves the following technical effects:

[0060] In the embodiment of the present application, an integrated setting is adopted, and the first electrode sheet 60 and the second electrode sheet 70 cause a corresponding redox reaction on the liquid to be reacted flowing through the reaction plate 30, thereby achieving the purpose of reducing the distance between the circulation pools between the cathode and anode electrodes, thereby achieving the technical effect of accelerating the rate of the cathode and anode two-stage redox reactions and improving the efficiency of the electrochemical reaction, thereby solving the technical problems of the existing electrochemical continuous flow reactor having a single function, low integration, complex operation, and the fact that the electrode materials and the size of the electrolytic cell are fixed and cannot meet the diverse usage requirements.

[0061] like Figure 5-6As shown, a first groove 101 matching the shape of the first conductive component 20 is provided in the first frame 10; an electrolyte inlet 102 for transferring the reaction liquid from the first frame 10 to the reaction plate 30 and an electrolyte outlet 103 for transferring the reaction liquid from the reaction plate 30 to the first frame 10 are provided on opposite sides of the first frame 10. It can be understood that by providing the first groove 101 on the first frame 10, a good assembly effect with the first conductive component 20 can be achieved; at the same time, the electrolyte inlet 102 and the electrolyte outlet 103 are provided on opposite sides of the first frame 10, respectively, which can achieve a good electrolyte inlet and outlet effect, and at the same time, can also achieve a good coordination effect with other components, thereby achieving the effect of increasing the liquid flow stroke. The electrolyte inlet and outlet are connected to the peristaltic pump pipeline using a peek (polyetheretherketone) special material pipe joint, which is corrosion-resistant. Preferably, the peristaltic pump flow pipeline is a corrosion-resistant silicone hose with an inner diameter of 4mm.

It can be understood that by respectively providing the first sealing groove 104 and the second sealing groove 301 on the opposite surfaces of the first frame 10 and the reaction plate 30, and providing the sealing ring 80 therein, a good sealing effect can be achieved, thereby avoiding the occurrence of liquid leakage.

[0064] Furthermore, a first through hole 105 is provided at the center of the first frame 10, and a plurality of first mounting holes 106 are provided around the first frame 10, and the first mounting holes 106 are located at the outer edge of the first sealing groove 104; a fourth through hole 502 is provided at the center of the second frame 50. It can be understood that by providing the first through hole 105, a good assembly effect with the first conductive component 20 can be achieved; at the same time, by providing a plurality of first mounting holes 106, a good fixed mounting effect between components can be achieved; and by providing the first mounting holes 106 at the outer edge of the first sealing groove 104, a good sealing effect can be ensured.

[0065] like Figure 3 and 9As shown, the first conductive component 20 includes: a first conductive graphite 201 embedded in the first groove 101, a first conductive connection hole 202 is provided at the center of the first conductive graphite 201 and close to the first frame 10, a first conductive connector 203 is provided in the first conductive connection hole 202, at least the bottom portion of which extends out of the outer surface of the first frame 10, and a first screwing member 204 is provided at the bottom of the first conductive connector 203, which is located on the outer surface of the first frame 10 away from the first conductive graphite 201, and a second through hole 2041 is provided on the first screwing member 204.

[0069] It should be noted that the thickness of the flow channel 303 determines the distance between the two electrodes, thereby achieving an effect that the distance between the two electrode sheets can be adjusted, thereby being able to meet the needs of various usage scenarios.

[0070] The width of the flow channel 303 is also the flow aperture. The width not only controls the flow rate, but also mainly controls the contact area between the liquid and the electrode. The contact area directly affects the efficiency of electron gain and loss, and affects the reaction rate. The larger the electrode contact area, the smaller the flow volume, and the greater the electron gain and loss rate;

[0071] The calculation formula is: electron gain and loss rate = electrode contact area / liquid volume.

Assembly screws: The electrochemical continuous flow reactor is assembled and fixed by four sets of screws and nuts. No tools are required and it can be quickly installed manually. In addition, two sets of nuts are used to fix it with conductive copper parts to prevent leakage.
