Potassium hydroxide is also known as caustic potash and caustic soda. Its chemical formula is KOH. The pure product is white rhombic crystal. The industrial product is white powder or flake solid. Potassium hydroxide has strong caustic corrosiveness. Its properties are similar to caustic soda. When exposed to air, it is easy to deliquesce with moisture in the air or absorb carbon dioxide in the air to generate potassium carbonate.
Potassium hydroxide is widely used in medicine industry, light industry, dyestuff industry, electrochemistry industry, metallurgy, and leather industry. The main raw materials for producing potassium hydroxide are potassium chloride and electric power, and China is one of the countries with poor potassium chloride resources, so it is necessary to introduce a large number of potassium chloride from abroad for production every year. Among the imported potassium chloride in China, the production of potassium hydroxide accounts for about 250000-300000 tons, accounting for one twentieth of the total import. Restricted by various factors, most of the potassium chloride purchased by the potassium hydroxide production plant is the source of transfer goods, so the factory price is high, which leads to the high cost of potassium hydroxide products in China.
According to incomplete statistics, China's potassium hydroxide production areas are mainly distributed in Shandong, Zhejiang, Jiangsu, Hubei and other places, and other individual areas also have potassium hydroxide manufacturers, which is relatively less concentrated than the distribution of the above areas.
