Products Description of Potassium Hydroxide CAS#1310-58-3

Potassium hydroxide is an inorganic compound with the chemical formula KOH. It is a common inorganic base with strong alkalinity. The pH of 0.1 mol/L solution is 13.5. It is soluble in water and ethanol, slightly soluble in ether, and easily absorbs moisture in the air to become deliquescent. It absorbs carbon dioxide to form potassium carbonate. It is mainly used as a raw material for the production of potassium salts, and can also be used in electroplating, printing and dyeing, etc.

Product Application of Potassium Hydroxide CAS#1310-58-3

Potassium hydroxide is mainly used as a raw material for the production of potassium salts, such as potassium permanganate, potassium carbonate, etc. In the pharmaceutical industry, it is used to produce potassium borohydride, spironolactone, safranolol, progesterone and testosterone propionate, etc. In the light industry, it is used to produce potassium soap, alkaline storage batteries, and 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 used in large quantities as the main raw material for the manufacture of artificial fibers and polyester fibers. In addition, it is also used in metallurgical heating agents and leather degreasing.
