What is Koh Potassium Hydroxide?

Koh Potassium Hydroxide is typically known as caustic potash, potash ash, etc. The commercial items are generally in 2 types, solid and liquid, of which the strong is white or light gray flakes and also bars, and also the fluid potassium hydroxide is a light yellow liquid. Similar in chemical homes to salt hydroxide, it is very alkaline and destructive, quickly soluble in water and also releases a lot of warm, and also has deliquescence residential or commercial properties, which can easily take in wetness airborne as well as deliquescence, as well as soak up carbon dioxide to develop potassium carbonate. A lot of warm is produced when dissolved in water, alcohol or treated with acid. The pH of the 0.1 mol/L solution is 13.5. (anhydrous). Reasonably hazardous, the typical dangerous dosage (rat, dental) is 1230 mg/kg. Currently, Koh Potassium Hydroxide is mostly made use of to synthesize potassium carbonate, potassium permanganate, and so on, and also is generally used in chemical, food, medicine, agriculture and also various other areas.

Koh Potassium Hydroxide can be divided right into food grade as well as industrial grade. Amongst them, industrial quality 99% potassium hydroxide is generally made use of in leather, papermaking, printing as well as dyeing, sewage therapy and also other fields; food quality potassium hydroxide is primarily made use of in pharmaceutical intermediates, different potassium salts, artificial additive active ingredients, food handling container cleansing, disinfection and other areas. Salt hydroxide and Koh Potassium Hydroxide are the raw products for making handcrafted soap. They are both solid alkalis. Nonetheless, after the hand-made soap is completed, its alkalinity becomes soap as a result of saponification with oil, as well as the alkalinity will remain to lower. After 1-2 After a month, its alkalinity goes down to also below 9, and it will not create major damages to the skin.

Koh Potassium Hydroxide Uses

1. In agriculture
① Koh Potassium Hydroxide is used to readjust soil pH.
② Made use of in the production of fertilizers to offer potassium for plants, especially those plants that can not tolerate chloride ions. ③ For herbicides as well as fungicides, as a mixture of phosphorous acid (a non-pesticide substance) and Koh Potassium Hydroxide, it can be regularly splashed to avoid pests and also diseases, and crops treated this way have virtually no pesticide deposits.

2. In the chemical sector
① Koh Potassium Hydroxide is mainly made use of as basic material for potassium salt production, such as potassium permanganate, potassium carbonate, potassium aluminate, laurate, formate, gluconate, etc ② Used to readjust the pH of chemical remedies, valuable reagents in chemical evaluation, such as in acid titrations (to aid establish focus levels). ③ It can also advertise drying, so it can be utilized as a desiccant to remove wetness in alkaline solvents, specifically amines as well as pyridines.

3. Chemistry laboratory
The Koh Potassium Hydroxide test helps find fungal infections on the skin as well as additionally aids in examining insect anatomy as it increases the procedure of breaking down soft tissues.

4. Petrochemical sector
① In the refining of oil and also gas, Koh Potassium Hydroxide assists to get rid of organic acids and also sulfur substances. ② When creating biodiesel from oil, it serves as a driver. ③ The co2, sulfur trioxide as well as nitrogen trioxide in the gas stream are absorbed with the help of potassium hydroxide.

5. Cosmetics sector
① Koh Potassium Hydroxide is made use of in the manufacture of nail items due to the fact that it assists to cleanse the nails and also liquify the follicle; ② It is made use of in cutting products to assist with hair removal; ③ The raw material for the production of creams, hair shampoos, hair sprays as well as various other cosmetics, generally made use of as pH regulator and also pH regulator. ③ Not only denture cleansers, but oven cleaners, driveway as well as concrete cleansers likewise include potassium hydroxide.

6. Food sector
① Koh Potassium Hydroxide is used to soften olives; ② It is a common artificial additive used to make sodas, chocolate and also chocolate, etc; ③ It can be made use of as a thickener as well as stabilizer for foods such as ice cream; ④ It additionally assists to make more crispy Baked food, can be added to food as a preservative; ⑤ utilized to produce tinted caramel; ⑥ made use of for cleaning and also chemical peeling of fruits and vegetables; ⑦ assists to prolong the service life of food.

7. Pharmaceutical and medical sector
① For the production of potassium borohydride, spironolactone, saparinol, testosterone propionate, and so on; ② for the damage of calf bone horn; ③ for the dissolution of warts and also follicle.

8. In the textile market: it is made use of as a lightening agent, as well as is widely utilized as the major raw material for the manufacture of man-made fibers and also polyester fibers.

9. In the color sector: made use of in the manufacturing of vat dyes, such as barrel blue RSN, and so on 10. In the natural leather market: Potassium hydroxide plays an important role in getting rid of hair from pet hides and also is present in natural leather tanning chemicals.

11. Cleansing items
Saponification of fats with Koh Potassium Hydroxide can be utilized to produce potassium soaps. While soaps made with sodium hydroxide are more usual, potassium soaps are softer as well as more soluble than these soaps. As a result, they include more detergent than liquefied sodium soap. This is why liquid soaps are potassium soaps and solid soaps are sodium soaps. Potassium hydroxide exists in non-phosphate detergents. Used in items for unclogging drains pipes as well as pipes.

12. In batteries and gas cells
① Battery: Potassium hydroxide dissolved in water is made use of as an electrolyte in alkaline batteries, nickel-cadmium batteries as well as manganese-zinc dioxide batteries; ② Fuel cell: As a gas cell electrolyte, Koh Potassium Hydroxide solution contrasted to sodium hydroxide solution far better electrical conductivity.

13. The pulp and paper sectors call for Koh Potassium Hydroxide, which helps different lignin from cellulose fibers as well as aids get rid of foam from paper manufacturing.

14. In various sectors, Koh Potassium Hydroxide is utilized to eliminate oil or oil from metals.

15. Additionally used in the manufacture of published circuit boards.

Production Method of Koh Potassium Hydroxide

The raw material potassium chloride of diaphragm electrolysis method is melted into a saturated solution in a salt-melting tank. When heated to 90 °C, potassium carbonate, caustic potash and barium chloride are added to remove impurities such as calcium, magnesium and sulfate radicals. After sedimentation, slag removal and hydrochloric acid neutralization , The refined potassium chloride solution containing potassium chloride 280~315g/L is preheated to 70~75℃ and then electrolyzed to obtain Koh Potassium Hydroxide, chlorine gas and hydrogen gas. The concentration of Koh Potassium Hydroxide obtained by the diaphragm method is 10% to 11%. It needs to be concentrated by evaporation and clarified by cooling to obtain a solution containing 45% to 50% of Koh Potassium Hydroxide; it can also be concentrated in a soda pot and decolorized to obtain Solid potassium hydroxide, or tableted Koh Potassium Hydroxide product. Its 2KCl+2H2O[electrolysis]→2KOH+C12↑+H2↑
The preparation of the electrolyte of the mercury electrolysis method is the same as that of the diaphragm electrolysis method. In the electrolysis chamber, graphite (or metal) is used as the anode, and mercury is used as the cathode. The chlorine generated by electrolysis is sent to the chlorine drying process, and the potassium amalgam generated flows into the mercury solution chamber. Most of the unreacted potassium chloride is treated in a light brine state and returned to the raw material dissolving process. Potassium amalgam reacts with water to form Koh Potassium Hydroxide and hydrogen. The concentration of potassium hydroxide from the mercury solution chamber is 45% to 50%, which can be used as a liquid potassium hydroxide product, or it can be distilled into a solid alkali or made into a flake Koh Potassium Hydroxide product. Its electrolysis and potassium amalgam to dissolve mercury
