Description

technical field [0001] The invention relates to the technical field of tetrabutylammonium hydrogensulfate preparation, in particular to a system and method for preparing high-purity tetrabutylammonium hydrogensulfate by electrolysis. Background technique [0002] Electrolysis is a method of redox reaction using direct current. The principle is that the current passes through the substance to cause a chemical change. The chemical change is the process in which the substance loses or obtains electrons (oxidation or reduction). During electrolysis, it is a device that converts electrical energy into chemical energy. It is an electrolytic cell, and the electrolysis process is carried out in an electrolytic cell. Electrolysis, this water treatment method includes electrochemical action on the surface of the electrode, indirect oxidation and indirect reduction (using chemical products generated near the electrode to chemically react with substances in the water) reaction), electri...

Disadvantages are: when processing a large amount of wastewater, it consumes electricity, consumes a large amount of electrode metal, and the separated sediment is not easy to process and utilize, etc. It is mainly used to treat chromium-containing and cyanide-containing wastewater, and remove oil, suspended solids, heavy metal ions and water in water. Decolorization treatment, etc., while tetrabutylammonium bisulfate can be used as a phase transfer catalyst, ion-pair chromatography reagent, methylene dicarboxylate, synthetic ether, indole N-alkane; it needs to be stored in a closed container, stored in Keep in a cool, dry, well-ventilated place away from incompatible substances

[0003] Chinese patent (notification number CN103014775B) a method and device for producing titanium by molten salt electrolysis discloses a method for producing titanium by electrolysis, which has achieved good preparation results; however, there are few existing documents Adopt electrolytic method to prepare tetrabutylammonium bisulfate, and the preparation method is not very mature, so the present invention further improves the electrolytic method through further research
