Uses and synthesis of Potassium hydroxide powder

Potassium hydroxide powder is commonly known as caustic potash, potassium ash, etc. There are two main forms of industrial products, respectively, solid and liquid, in which the solid state is white or light gray flakes, lumps and rods, and the liquid potassium hydroxide is a light yellow liquid.\

Potassium hydroxide CAS 1310-58-3 Chemical properties are similar to sodium hydroxide, it has strong alkalinity and corrosiveness, easily soluble in water and will be a lot of exothermic, and Potassium hydroxide Raw Materials has deliquescence, it is easy to absorb moisture in the air and deliquesce, and absorb carbon dioxide and become potassium carbonate.

Applications / Functions of Potassium hydroxide powder

1. Potassium hydroxide Raw Materials are mainly used as raw materials for the production of potassium salts, such as potassium permanganate and potassium carbonate.
2. In the pharmaceutical industry, Potassium hydroxide powder is used in the production of potassium borohydride, amphotericin, salvinorin, progesterone and testosterone propionate.
3. In light industry, Potassium hydroxide CAS 1310-58-3 is used in the production of potassium soap, alkaline storage battery, cosmetics (such as cold cream, snow cream and shampoo).
4. In the dyestuff industry, Potassium hydroxide Raw Materials is used for the production of reducing dyes, such as reducing blue RSN. In the electrochemical industry, it is used in electroplating and engraving.
5. In the textile industry, Potassium hydroxide powder is used for printing and dyeing, bleaching and mercerizing, and is used as the main raw material for the manufacture of synthetic fiber and polyester fiber.
6. In addition, Potassium hydroxide CAS 1310-58-3 is also used in metallurgical heating agent and leather degreasing.

Physicochemical Property of Potassium hydroxide powder

White rhombohedral crystal, white or light gray lumps or rods in industry. Potassium hydroxide powder is soluble in water, soluble in ethanol, slightly soluble in ether.

Potassium hydroxide Raw Materials Commonly known as caustic potash, potassium ash, etc., industrial products are mainly in two forms, respectively, solid and liquid, of which the solid state is white or light gray flakes, lumps and rods, and the liquid potassium hydroxide is a light yellow liquid.

The chemical property is similar to sodium hydroxide, with strong alkaline and corrosive, Potassium hydroxide CAS 1310-58-3 is soluble in water and will be a lot of exothermic, and also has deliquescence, it is very easy to absorb moisture in the air and deliquesce, and absorb carbon dioxide and become potassium carbonate.

Generate a lot of heat when dissolved in water, alcohol or treated with acid. pH of 0.1mol/L solution is 13.5 (anhydrous). Moderately toxic, LD50 (rat, orally) 1230mg/kg.Currently Potassium hydroxide CAS 1310-58-3 is mainly used to synthesize potassium carbonate, potassium permanganate and so on, which are mainly used in many fields such as chemical industry, foodstuffs, medicine and agriculture.

Production methodprocess of Potassium hydroxide powder

• Diaphragm electrolysis raw material potassium chloride is dissolved into saturated solution in the salt bath, when heated to 90℃, add potassium carbonate, caustic potash, barium chloride to remove impurities such as calcium, magnesium and sulphate etc., and then after settling and removing dregs, hydrochloric acid neutralization and refining, the potassium chloride solution containing potassium chloride of 280-315g/L is preheated to 70-75℃ and then proceeded to electrolysis, and Potassium hydroxide powder, chlorine gas and hydrogen gas can be obtained. powder, chlorine gas and hydrogen gas.
• The concentration of Potassium hydroxide Raw Materials obtained by the diaphragm method is 10% to 11%, which needs to be clarified by evaporation, concentration and cooling to produce a solution containing 45% to 50% potassium hydroxide; it can also be continued to be concentrated in the boiling pot of alkali, and then be decolorized to produce solid potassium hydroxide, or be made into flakes of Potassium hydroxide Raw Materials. Materials 
• The preparation of electrolyte for mercury electrolysis is the same as that for diaphragm electrolysis. Graphite (or metal) is used as the anode and mercury as the cathode in the electrolysis chamber. Chlorine generated from electrolysis is sent to the chlorine drying process, and the generated potassium amalgam flows into the mercury decomposition chamber. Most of the unreacted potassium chloride is treated in the state of light brine and returned to the raw material dissolution process.

Potassium amalgam reacts with fresh water to form Potassium hydroxide CAS 1310-58-3 and hydrogen. Since the concentration of potassium hydroxide coming out of the mercury dissolution chamber is 45%~50%, it can be used as liquid potassium hydroxide product, or it can be vaporized and concentrated into solid alkali or made into flake potassium hydroxide CAS 1310-58-3 through alkali boiling kettle.
