1. It is used as desiccant, absorbent, oxalic acid and various potassium salts, as well as electroplating, engraving, lithography, etc.
2、主要用作鉀鹽生產的原料，如高錳酸鉀、碳酸鉀等。在醫藥工業中，用于生產鉀硼氫、安體舒通、沙肝醇、丙酸睪丸素等。在輕工業中用于生產鉀肥皂、堿性蓄電池、化妝品（如冷霜、雪花膏和洗發膏）。在染料工業中，用于生產還原染料，如還原藍RSN等。
2. It is mainly used as raw material for potassium salt production, such as potassium permanganate, potassium carbonate, etc. In the pharmaceutical industry, it is used to produce potassium borohydride, spironolactone, salganol, testosterone propionate, etc. In light industry, it is used to produce potassium soap, alkaline batteries, cosmetics (such as cold cream, cream and shampoo). In the dye industry, it is used to produce vat dyes, such as vat blue RSN, etc.
在電化學工業中，用于電鍍、雕刻等。在紡織工業中，用于印染、漂白和絲光，并大量用作制造人造纖維、聚酯纖維的主要原料。此外，還用于冶金加熱劑和皮革脫脂等方面。
In the electrochemical industry, it is used for electroplating, engraving, etc. In the textile industry, it is used for printing and dyeing, bleaching and mercerization, 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 agents and leather degreasing.
性質與穩定性
Properties and stability
1、易潮解。暴露于空氣中時，易吸收二氧化碳和水分，逐漸變成碳酸鉀。易溶于水，溶解時放出大量溶解熱，有很強的吸水性，在空氣中能吸收水分而溶解，并吸收二氧化碳逐漸變成碳酸鉀。溶于乙醇，微溶于醚。有很強的堿性和腐蝕性，其性質與燒堿相似。能引起灼傷。易于吸收空氣中的水分和CO2。
1. Deliquescent. When exposed to the air, it is easy to absorb carbon dioxide and water, and gradually turns into potassium carbonate. It is easy to dissolve in water, emits a lot of heat of dissolution when dissolving, and has strong water absorption. It can absorb water and dissolve in the air, and absorb carbon dioxide to gradually turn into potassium carbonate. Soluble in ethanol, slightly soluble in ether. It is highly alkaline and corrosive, and its properties are similar to caustic soda. Can cause burns. Easy to absorb moisture and CO2 in the air.
