Potassium dihydrogen phosphate is an inorganic compound with the chemical formula KH2PO4, which is deliquescent and melts when heated to 400 ℃ to form a transparent liquid. After cooling, it solidifies into an opaque glassy potassium metaphosphate. Stable in air, soluble in water, insoluble in ethanol. Used as a buffer and culture agent in industry, as well as a seasoning agent for bacterial culture in the synthesis of sake, as a raw material for the production of potassium metaphosphate, as a culture agent, enhancer, leavening agent, and fermentation assistant for brewing yeast, and as a high-efficiency phosphorus potassium compound fertilizer in agriculture.
Used as a buffer and culture agent in industry; It is also used as a seasoning agent for bacterial culture synthesis, a raw material for the production of potassium metaphosphate, a culture agent, enhancer, leavening agent, and fermentation assistant for brewing yeast.
Agricultural use
Used as an efficient phosphorus potassium compound fertilizer in agriculture; Potassium dihydrogen phosphate products are widely applicable to almost all types of crops, including economic crops, grains, fruits, vegetables, etc. In each province, expert institutions such as local agricultural science academies and soil fertilizer stations have conducted many related application experiments on the applicability of potassium dihydrogen phosphate to various typical crops. Through the actual application effects of various types of crops in various regions, it has been proven that potassium dihydrogen phosphate has significant yield and income increase, improved quantity and quality, and resistance to lodging It has many excellent effects such as disease and pest resistance, prevention and control of premature aging, and has the ability to overcome nutrient deficiencies caused by the aging and absorption capacity of roots in the later stages of crop growth. Potassium dihydrogen phosphate is a new type of high concentration phosphorus potassium two element compound fertilizer, which contains about 52% phosphorus pentoxide and about 34% potassium pentoxide. Flue-cured tobacco requires a large amount of phosphorus and potassium, especially potassium. Potassium dihydrogen phosphate is an ideal new type of fertilizer for flue-cured tobacco. To explore the value and application methods of potassium dihydrogen phosphate in flue-cured tobacco, in order to improve the quality of tobacco leaves. Potassium dihydrogen phosphate used on cotton can control cotton elongation and increase the number of plant flower buds. Potassium dihydrogen phosphate is widely used in drip irrigation systems.
