Introduction (Potassium hydroxide,CAS NO.1310-58-3)
Potassium hydroxide is an inorganic compound with the formula KOH, and is commonly called caustic potash.
KOH is a prototypical strong base. It has many industrial and niche applications, most of which exploit its caustic nature and its reactivity toward acids.
KOH is noteworthy as the precursor to most soft and liquid soaps, as well as numerous potassium-containing chemicals. It is a white solid that is dangerously corrosive.
KOH exhibits high thermal stability. Because of its high stability and relatively low melting point, it is often melt-cast as pellets or rods, forms that have low surface area and convenient handling properties.

1. Used as desiccant and absorbent, used to make oxalic acid and various potassium salts, and also used in electroplating, engraving, lithography, etc.
2. Mainly used as raw material for potassium salt production, such as potassium permanganate, potassium carbonate, etc. In the pharmaceutical industry, it is used for the production of potassium borohydride, spironolactone, saparinol, testosterone propionate, etc. In light industry, it is used to produce potassium soap, alkaline storage battery, cosmetics (such as cold cream, vanishing cream and shampoo). In the dye industry, it is used to produce vat dyes, such as vat blue RSN, etc. In the electrochemical industry, it is used for electroplating, engraving, etc. In the textile industry, it is used for printing and dyeing, bleaching and mercerizing, and is widely used as the main raw material for the manufacture of man-made fibers and polyester fibers. In addition, it is also used in metallurgical heating agent and leather degreasing.
3. Basic chemical raw materials, used in medicine, daily chemicals, etc.
4. Used as an absorbent for analytical reagents, saponification reagents, carbon dioxide and moisture.
5. The daily chemical industry is used as the raw material for the manufacture of detergent soap, shampoo soft soap, vanishing cream, cold cream, shampoo, etc. The pharmaceutical industry is used to manufacture raw materials such as progesterone and vanillin. The dye industry is used to manufacture melamine dyes. The battery industry is used to manufacture alkaline storage batteries.
