تری سدیم فسفات انهیدروس

Trisodium phosphate anhydrous is a white, granular or crystalline inorganic compound widely used as a strong alkaline agent and buffering agent in laboratory and pharmaceutical formulations. It is valued for its high solubility in water and effectiveness in pH adjustment and cleaning applications.

🏭⚗️ Production
It is produced by neutralizing phosphoric acid with sodium hydroxide followed by evaporation and drying to remove water, yielding the anhydrous form. The resulting compound is purified to meet laboratory or pharmaceutical standards.

🔬 Properties
The chemical formula is Na₃PO₄ with a molar mass of approximately 163.94 g/mol. It appears as a white, odorless solid that dissolves readily in water, producing a strongly alkaline solution (pH > 12). It is hygroscopic and should be stored carefully to avoid moisture absorption. The compound is stable under normal storage but decomposes on heating to release sodium oxides and phosphorus oxides.

🧪 Applications
In laboratories, trisodium phosphate anhydrous is used for pH control, buffer preparation, and as a cleaning agent to remove grease and stains from glassware and instruments. In pharmaceutical contexts, it is used in formulation processes requiring alkaline conditions and as a source of phosphate ions. It is also used in detergents, water treatment, and food additives.

⚠️ Safety
Trisodium phosphate anhydrous is corrosive and can cause severe skin and eye irritation or burns upon contact. Inhalation of dust may irritate the respiratory tract. Proper personal protective equipment such as gloves, goggles, and dust masks should be used when handling. It should be stored in airtight containers in a cool, dry place, away from acids and moisture.
