Applications
1. Food Industry: Acts as an emulsifier, stabilizer, and pH regulator in processed foods and beverages.
2. Pharmaceuticals: Used as a buffering agent in medicinal formulations and saline solutions.
3. Water Treatment: Functions as a softening agent and corrosion inhibitor.
4. Chemical Industry: Used in the production of detergents, ceramics, and electroplating solutions.
5. Agriculture: Provides phosphorus for fertilizer formulations.
Production Technology
Anhydrous DSP is produced by the neutralization of phosphoric acid with sodium hydroxide or sodium carbonate, followed by controlled drying processes to remove all water content. Advanced quality control measures ensure high purity and consistency.
Theory
Anhydrous DSP dissociates in water to provide HPO₄²⁻ ions, serving as an effective buffer to stabilize pH levels. Its anhydrous form ensures optimal performance in moisture-sensitive applications and facilitates precise control in chemical reactions.
