Potassium dihydrogen phosphate is widely used in industry, agriculture, animal husbandry, medicine and chemical industry. In agriculture, it is a highly effective chlorine-free phosphorus and potassium salt that provides not only phosphorus but also potassium to crops, significantly improving their drought and cold tolerance while significantly increasing yields. The preparation of potassium dihydrogen phosphate by wet phosphoric acid extraction, through the direct reaction of wet phosphoric acid with inorganic potassium salt, and the use of centrifugal solvent extraction to remove the inorganic acid, after concentration, crystallization and washing to remove impurities, the final product of high purity potassium dihydrogen phosphate.

Compared with the traditional neutralization process, the centrifugal solvent extraction of potassium dihydrogen phosphate has obvious advantages. It uses wet process phosphoric acid and potassium chloride as raw materials, which greatly reduces the production cost and has remarkable economic benefits. This new process has strong competitiveness and is one of the important technical directions for the future development of potassium dihydrogen phosphate industry. The process of centrifugal solvent extraction of potassium dihydrogen phosphate is helpful to change the high cost of traditional neutralization process and improve the development level of potassium dihydrogen phosphate industry in China.

Ammonium dihydrogen phosphate (MAP) above industrial grade is a widely used product with growing demand in agriculture, fire protection, food, phosphate optical glass, lithium battery positive materials and other fields. The traditional thermal ammonium phosphate neutralization process to prepare industrial MAP has the problems of high energy consumption, high pollution and high cost, and has gradually lost its competitive advantage in the market.

However, in recent years, the industrial MAP process for purifying wet phosphoric acid production with solvent extraction method as the core equipment has shown great technical advantages. By optimizing the process flow and integrating the process of stripping, phosphoric acid concentration, ammonification, crystallization and separation, the product obtained is of high purity and excellent quality, and the production is highly automated.

Centrifugal solvent extraction is of great significance to accelerate the transformation and upgrading of phosphate fertilizer enterprises and the development of fine phosphorus chemical products. The product has high purity, high yield of potassium dihydrogen phosphate, and economic and environmental protection, laying a solid foundation for the further development of potassium dihydrogen phosphate industry. Let's meet the technological innovation of centrifugal solvent extraction and lead the future of phosphoric acid chemical industry!
