Embodiment 1
[0065] refer to figure 1 , 6 , 7, 8, a kind of 3, the electrolytic synthesis equipment of 6-dichloropicolinic acid, comprise power supply 1, batching tank 12, electrolyzer 5, described power supply 1 is the periodic reversing power supply of voltage-stabilizing silicon controlled rectifier, The power supply 1 is connected to a current commutator 2, and the current commutator 2 is provided with a program control unit; the positive pole of the power supply 1 is connected to the anode of the electrolyzer, and the negative pole of the power supply 1 is connected to the cathode of the electrolyzer.
[0066] The anode is composed of a tab 40 , a rhombus mesh plate 41 and a current collector 42 . The cathode is supported by a polypropylene substrate 54 . The anode plate has a longitudinal diamond-shaped network structure, and the cathode plate has a transverse diamond-shaped network structure. The diamond-shaped network structure is formed by connecting a plurality of identical par...
Embodiment 2
[0070] refer to figure 1 , 6 , 7, 8, the only difference between this embodiment and embodiment 1 is the size of the electrolytic cell. The electrolytic cell of the present embodiment adopts the box-type electrolytic cell with a volume of 1200ML. In the electrolytic cell, a vertical rhombic mesh Hastelloy C-276 nickel alloy anode and a zigzag rhombic silver mesh cathode are placed in parallel. The distance between the electrodes is 2cm. Total working area 100cm 2 , the total area of cathode macro work is 100cm 2 , anode size: macro length, width and thickness are 10.0cm×10.0cm×0.3cm, Ts is 1mm, LWD is 5mm, SWD is 2mm, Ws is 3mm; cathode size: macroscopic length, width and thickness are 10.0cm×10.0 cm×0.2cm, Ts is 0.5mm, LWD is 2mm, SWD is 1mm, Ws is 1.5mm.
[0071] Add 50g of 3,4,5,6-tetrachloropicolinic acid, 50g of sodium hydroxide and 1000ML of deionized water into the electrolytic cell. After dissolving, turn on the magnetic pump (the flow rate is 5.5-6.5L / min) to ci...
Embodiment 3
[0073] refer to figure 1 , 3 , 4, 6, 7, 8, a kind of electrolytic synthesis equipment of 3,6-dichloropicolinic acid, comprising a power supply 1, a batching tank 12, and an electrolytic tank 5, and the power supply is a voltage-stabilizing and current-stabilizing thyristor periodically changing To the power supply, the power supply 1 is connected to the current commutator 2, and the current commutator is provided with a program control unit; the positive pole of the power supply 1 is connected to the anode of the electrolyzer, and the negative pole of the power supply 1 is connected to the cathode of the electrolyzer.
[0074] The electrolyzer of this embodiment adopts image 3 A single-stage electrolyser in a battery of box-type electrolysers without diaphragms shown. The interior of the unipolar electrolytic cell is provided with 2 pieces of longitudinal diamond-shaped mesh Hastelloy C-276 nickel alloy as anodes and 1 piece of horizontal diamond-shaped silver mesh as catho...
