Use of potassium hydroxide
[Purpose 1]
Basic chemical raw materials, used in pharmaceuticals, daily chemical industry, etc.
【 Purpose 2 】
Used as a desiccant, absorbent, in the production of potassium soap, oxalic acid, and various potassium salts, as well as in electroplating, carving, lithography, and other applications
[Purpose 3]
Used as an absorbent for analytical reagents, saponification reagents, carbon dioxide, and water, as well as in the pharmaceutical industry
【 Purpose 4 】
It is mainly used as raw material for potash production, such as Potassium permanganate, potassium carbonate, etc. In the pharmaceutical industry, it is used to produce potassium borohydride, spironolactone, salbutamol, progesterone, and testosterone propionate. Used in the production of potassium soap, alkaline batteries, cosmetics (such as cold cream, snow cream, and shampoo) in light industry. In the dye industry, it is used to produce Vat dye, such as vat blue RSN. In the electrochemical industry, it is used for electroplating, carving, etc. In the Textile manufacturing, it is used for printing, dyeing, bleaching and mercerizing, and is widely used as the main raw material for manufacturing man-made fibers and polyester fibers. In addition, it is also used in metallurgical heating agents and leather degreasing.
【 Purpose 5 】
Adjust the pH value of the solution through acid-base neutralization. Basic chemical reagents, carbon dioxide absorbents. Saponification agent.

Storage conditions
Storage precautions: Store in a cool, dry, and well ventilated warehouse. Keep away from sparks and heat sources. The temperature of the warehouse shall not exceed 35 ℃, and the relative humidity shall not exceed 80%. The packaging must be sealed and protected from moisture. It should be stored separately from flammable (combustible) substances, acids, etc., and mixed storage should be avoided. The storage area should be equipped with suitable materials to contain leaks.
Stability
1. Easy to deliquescence. When exposed to the air, it is easy to absorb carbon dioxide and water, gradually turning into potassium carbonate. Easily soluble in water, it emits a large amount of Enthalpy change of solution when dissolving, and has strong water absorption. It can absorb water in the air to dissolve, and absorb carbon dioxide to gradually become potassium carbonate. Soluble in ethanol, slightly soluble in ether. It has extremely strong alkalinity and corrosiveness, and its properties are similar to those of caustic soda. Can cause burns. Easy to absorb moisture and CO2 from the air.
2. Stability and stability
3. Prohibited substances: strong acids, flammable or combustible substances, carbon dioxide, anhydride, acyl chloride
4. Conditions to avoid contact with damp air
5. Polymerization hazard: non polymerization
6. Decomposition product Potassium oxide
