Affected by the tightening of environmental protection policies, the structure of the potassium dihydrogen phosphate industry has been continuously optimized, and the supply and demand relationship has become more balanced.
The chemical formula of potassium dihydrogen phosphate is KH2PO4, with a molecular weight of 136.09. It is a five-color or white glossy rhomboid. It is soluble in water. The aqueous solution shows an acidic reaction, is slightly soluble in alcohol, has hygroscopic and deliquescent properties, and melts when heated to 400°C. It becomes a transparent liquid and solidifies into an opaque glassy substance potassium metaphosphate (KPO3) after cooling.
Potassium dihydrogen phosphate is widely used in chemical, pharmaceutical, food, agriculture, petroleum, papermaking, detergent and other industries due to its special properties. In the chemical industry, it is mainly used as bacterial culture agent, brewing yeast culture agent, flavoring agent, etc.; in medicine, it is used as a nutritional agent to acidify urine; in the food industry, it is one of the important varieties of food phosphates and is used for quality improvement. Agent, fermentation accelerator, nutritional fortifier, flavoring agent, chelating agent, buffer and used as a leavening agent together with dipotassium hydrogen phosphate; in agriculture, potassium dihydrogen phosphate is a high-concentration and efficient phosphorus-potassium compound fertilizer. High quality chlorine-free potassium fertilizer.
There are many production processes for potassium dihydrogen phosphate, including neutralization method, extraction method, ion exchange method, metathesis method, direct method, crystallization method and electrolysis method, etc. At this stage, the neutralization method is mostly used in the production of potassium dihydrogen phosphate in my country.
At present, the production capacity of potassium dihydrogen phosphate industry is mainly concentrated in China, Europe and North America. Among them, China is the main producer of potassium dihydrogen phosphate. The main enterprises in China’s potassium dihydrogen phosphate industry include Sinochem Fuling Chemical and Sichuan Lanjian. Chemical industry and Wuhan inorganic salt chemical industry, etc. However, although the output of my country’s potassium dihydrogen phosphate industry is high, because the industry mainly adopts the relatively high-cost neutralization production process, the production technology is relatively backward, and the product price is high, making its promotion in the agricultural field more difficult.
According to the “In-depth Investigation and Analysis Report on Market Supply and Demand Status and Industry Operating Indicators of the Potassium Dihydrogen Phosphate Industry from 2020 to 2026” released by the Industrial Research Center Shows that my country is the main producer of potassium dihydrogen phosphate. However, in recent years, with the tightening of domestic environmental protection policies, high-pollution and high-energy-consuming enterprises have gradually been closed. The scale of the potassium dihydrogen phosphate industry has slowed down, and the industry structure has slowed down. With continuous optimization, the relationship between supply and demand gradually becomes balanced.
Industrial researchers personnel said that in recent years, with the continuous development of food, medicine, pesticide and other industries, the market demand for potassium dihydrogen phosphate has also continues to grow. However, due to factors such as high production costs and environmental protection, the penetration rate of potassium dihydrogen phosphate in pesticides and other fields is low, and there is large room for development in the future. In the future, my country’s potassium dihydrogen phosphate industry should focus on developing low-cost, high-purity, and specialized potassium dihydrogen phosphate products to further expand its application areas.
