High Quality ammonium dihydrogen phosphate with CAS number 7722 - 76 - 1 is a white crystalline powder. It has a molecular formula of NH₄H₂PO₄ and a molecular weight of approximately 115.03 g/mol. The product is highly soluble in water and slightly soluble in ethanol. It has a density of around 1.803 g/cm³ at 19°C. This ammonium dihydrogen phosphate is known for its high purity level, which ensures reliable performance in various applications.
This ammonium dihydrogen phosphate has a wide range of applications. In the agricultural field, it is commonly used as a high - quality fertilizer. It provides both nitrogen and phosphorus, two essential nutrients for plant growth. Nitrogen promotes lush foliage and overall plant vigor, while phosphorus is crucial for root development, flower and fruit production. It can be applied to various crops, including cereals, fruits, and vegetables.
In the food industry, it serves as a food additive. It can be used as an acidity regulator, buffer, and nutrient supplement. For example, it can be added to certain processed foods to adjust the pH value and improve the stability and quality of the products.
In the fire - retardant industry, ammonium dihydrogen phosphate is an effective flame retardant. It can be used to treat textiles, wood, and paper products to enhance their fire - resistant properties. When exposed to fire, it decomposes and releases non - flammable gases, which can dilute the oxygen concentration around the combustible materials and suppress the spread of fire.
When using it as a fertilizer, it can be broadcast on the soil surface and then incorporated into the soil before planting or applied as a top - dressing during the growing season. The application rate depends on the type of crop, soil fertility, and growth stage. Generally, for field crops, the application rate can range from 10 - 20 kg per hectare. It should be evenly distributed to ensure uniform nutrient supply.
As a food additive, it should be used in accordance with the relevant food safety regulations. The usage amount should be strictly controlled within the specified limits. It can be added during the food processing process, and proper mixing is required to ensure its uniform distribution in the food product.
For fire - retardant treatment, the product can be dissolved in water to form a solution. The concentration of the solution depends on the specific application requirements. The materials to be treated can be soaked in the solution for a certain period of time or sprayed with the solution. After treatment, the materials should be dried thoroughly to remove the excess moisture.
Agricultural Case: A farmer in a large - scale wheat farm applied High Quality ammonium dihydrogen phosphate as a base fertilizer before sowing. The application rate was 15 kg per hectare. During the growth period, the wheat showed stronger tillering ability and healthier root systems compared to the fields without this fertilizer application. At the harvest time, the yield of the treated wheat increased by about 15% compared to the control group, and the quality of the wheat grains was also improved, with higher protein content.
Food Industry Case: A food processing company added ammonium dihydrogen phosphate as an acidity regulator in a fruit juice beverage production. By adding an appropriate amount of the product, the pH value of the juice was adjusted to an optimal range, which improved the taste and stability of the beverage. During the shelf - life test, the beverage maintained its quality and did not show significant changes in color and flavor.
Fire - retardant Case: A furniture manufacturing company treated wooden furniture parts with a solution of ammonium dihydrogen phosphate. After the treatment, the furniture parts were tested in a fire - safety laboratory. The results showed that the treated parts had a significantly longer ignition time and slower fire spread rate compared to the untreated parts, meeting the fire - safety standards of the market.
