Physical and Chemical Properties Potassium hydroxide is usually sold as translucent pellets, which become tacky in air because KOH ishygroscopic. Consequently, KOH typically contains varying amounts of water (as well as carbonates - see below). Its dissolution in water is strongly exothermic. Concentrated aqueous solutions are sometimes called potassium lyes. Even at high temperatures, solid KOH does not dehydrate readily.

Application 1. Used for electroplating, carving, lithography, etc. 2. Used as raw material for potassium salt production, such as potassium permanganate and potassium carbonate. 3. In the pharmaceutical industry, it is used to produce potassium borohydride, spironolactone, saparinol, testosterone propionate, progesterone, vanillin, etc. 4. Used in the production of potassium soap, alkaline storage batteries and cosmetics in the light industry. 5. In the dye industry, it is used to produce vat dyes, such as vat RSN. 6. Used as an absorbent for analytical reagents, saponification reagents, carbon dioxide and water. 7. In the textile industry, it is used for printing and dyeing, bleaching and mercerizing, and is mainly used as the main raw material for manufacturing man-made fibers and polyester fibers. It is also used for manufacturing melamine dyes. 8. It is also used in metallurgical heating agent and leather degreasing.
Storage Potassium hydroxide easily gets damp and decomposed. Once coming into contact with the air, it will absorb carbon dioxide from the air and become degraded. It should therefore be stored in a dry place with intact packaging to keeep it from becoming damp. And it should be stored and carried separately from any acids. Aluminum, tin, lead, zine and its alloys, explosives, peroxides, ammonium salts,inflammables,etc.Puring transportation it should be protected with covering, handle it with care to avoid packaging damage.
