25KG/BAG White Crystal Mono Potassium Phosphate For Fertalizer CAS 7778-77-0
White Potassium dihydrogen phosphate colorless is tetragonal crystal or white crystalline powder, deliquescent, soluble in water, insoluble in ethanol, low toxicity, health hazard level 1. Aqueous solutions are acidic, and a 1% potassium dihydrogen phosphate solution has a pH of 4.6. When heated to 400°C, it melts into a transparent liquid and solidifies into opaque glassy potassium metaphosphate after cooling.
It is produced by reacting an appropriate amount of phosphoric acid with potassium carbonate. Or by the calculated amount of phosphoric acid and potassium hydroxide solution reaction, and then decolorization, filtration, concentration, cooling, crystallization, centrifugal separation and drying.
Industrial grade potassium dihydrogen phosphate products are widely used in the application field, the specific uses in the main industries are: agriculture as a high-efficiency phosphorus potassium fertilizer, and potassium dihydrogen phosphate products are widely used in all types of cash crops, food, melons, fruits, vegetables and other almost all types of crops; In the food industry, potassium dihydrogen phosphate is used as a baking food additive and a nutritional flavoring additive. As a chemical raw material for the production of potassium pyrophosphate and other potassium salts in the chemical industry; It is used as a frequency doubling material in the optical field.
