Potassium Dihydrogen Phosphate is a high-efficiency phosphorus-potassium compound fertilizer and a versatile functional additive, known for its high nutrient content, excellent water solubility, and superior buffering capacity. It serves as a crucial input in precision agriculture, the food industry, and various industrial processes. The product is typically manufactured through the neutralization of food-grade or technical-grade phosphoric acid with potassium hydroxide, followed by crystallization, purification, and drying.
Product Specifications
Aliases: Monopotassium Phosphate, MKP
English Name: Potassium Dihydrogen Phosphate
Chemical Formula: KH₂PO₄
Molecular Weight: 136.09
CAS Number: 7778-77-0
Key Properties: High water solubility, acidic solution, strong buffering capacity, high nutrient content (P₂O₅ & K₂O)
Advanced Application Scenarios
1. High-Efficiency Nutrient Source in Precision Agriculture
Used in fertigation and foliar feeding systems, providing readily available phosphorus and potassium, with nutrient utilization efficiency exceeding 80%.
Serves as a key component in high-quality water-soluble fertilizers, often blended with nitrogen and micronutrients to create balanced formulations for specific crop needs.
2. Food Quality Improver in Food Industry
Acts as an emulsifier, stabilizer, and pH regulator in processed cheese, preventing oil separation and improving texture.
Used in meat products as a water-binding agent, enhancing juiciness and yield.
3. Buffer and Nutrient in Biotechnology
Serves as a crucial component in cell culture media and fermentation broths, providing essential phosphorus and potassium while maintaining stable pH.
Used in the preparation of buffer solutions in molecular biology and diagnostic kits.
4. Flame Retardant and Additive in Industrial Chemistry
Acts as an effective flame retardant in textiles and polymers, promoting char formation.
Used as a precursor for the production of other potassium phosphates and specialty chemicals.
Technological Breakthroughs and Sustainable Development
Purification Technology
Implementation of multi-stage purification and crystallization control technologies results in products with low heavy metal content (e.g., Pb ≤ 2 ppm, As ≤ 1 ppm), suitable for food and pharmaceutical grades.
Development of continuous neutralization processes improves production efficiency and product consistency.
Heat recovery systems in crystallization and drying units reduce energy consumption per ton of product.
Sustainable Practices
