Dodecahydrate Trisodium Phosphate Na3PO4 .12H2O
- CAS NO.: 7601-54-9
- HS Code: 28352910
- MF: Na3PO4.12H2O
- Main contents, Na3PO4 %: ≥98%
Trisodium phosphate dodecahydrate with the chemical formula of Na3PO4. 12H2O is white or colorless crystals in appearance. When it is heated to 100℃, it will lose 12 crystal water and become trisodium phosphate anhydrous. It is soluble in water and the aqueous solution is strongly alkaline, which has a certain corrosive effect on the skin. Please take care when using.

Preparation Process
Extraction Phosphoric Acid Method
The phosphate rock powder and sulfuric acid are reacted to obtain the extracted phosphoric acid. Then add an appropriate amount of washing water, dilute to make the phosphorus pentoxide content in the solution be 18% to 20%. Under stirring, slowly add B6 sodium carbonate with the temperature of 30-35℃ for neutralization reaction to make the PH value be 8 to 8.4. Then add the mother liquor of trisodium phosphate to make the content of phosphorus pentoxide in the solution be less than 12%. Keep the temperature for 15-20min, then it it filtered and concentrated by evaporation. Add liquid caustic soda to make the sodium storage ratio reach 3.24 to 3.26. After cooling, crystallization, centrifugal separation and airflow drying, the finished product of trisodium phosphate dodecahydrate is obtained.
