A stirring type fluorination electrolytic cell

Abstract

A stirring type fluorination electrolytic cell, which consists of a motor, a shaft coupling, a stirring shaft, a shaft seal, an electrode column, an electrode bundle, an electrolytic cell, an electrolytic cell cover plate, an electrolytic cell jacket, a shaft sleeve, a blind plate, and a guide tube , a stirring paddle, and an insulating gasket. The agitated fluorination electrolytic cell provided by the present invention makes the material dissolve and disperse more uniformly in the whole system, and at the same time, the fluorination reaction is carried out in the electrolytic cell, which reduces the reaction induction period. The reaction induction period is reduced from 3-5 days to one day, and the dead tank phenomenon is basically eliminated, and the number of times to clear the tank due to the treatment of dead tanks is reduced. Before adopting the stirring tank, the dead tank was 3-4 times a year. After the present invention is adopted, There is no dead tank phenomenon, the material consumption is reduced by more than 20%, the output of a single tank is increased by 30%, the polymer generated in the electrolytic tank is reduced, the tank cleaning time is doubled, and the labor intensity of manual tank cleaning is reduced.

Description

Technical field [0001] The invention relates to the technical field of an electrolytic cell for organic electrochemical synthesis, in particular to a stirred type fluorinated electrolytic cell. Background technique [0002] There are very few fluorine-containing organics in nature. How to introduce fluorine into organics has become an urgent problem that people need to solve. The preparation of organic fluorides can use F 2 Direct fluorination, XeF also available 2 , Hypofluoric acid, high-valent metal fluorides, N2F compounds and other fluorinating reagents indirect fluorination method. These chemical fluorination methods are complex in reaction and operation, and require harsh equipment; the fluorinating reagents used are highly toxic or extremely unsafe, and some are very expensive; and it is difficult to control the amount of fluorine added, and it is difficult to obtain the target product. Therefore, people have to find other methods. In 1941, American chemist Simons invent...

Problems solved by technology

However, the traditional electrolytic cell has the following disadvantages: the HF in the cell does not flow, and the electrolyte dissolved in the HF has a small contact with the plate, so the efficiency of the electrolytic fluorination reaction is low; the induction period of the reaction electrolytic fluorination reaction is long, generally 3 Days - 5 days, and the dead slot phenomenon is more frequent, after the voltage is applied, there is no current input
