Detailed Description:
Cas No. :7601-54-9
we are TSP manufacturer
1.Molecular formula: Na3PO4.12H2O
2.white crystal
Molecular formula: Na3PO4.12H2O
Molecular weight: 380.12
Properties: Colourless or white crystal, relative density is 1.62, melting point is 73.3 to 76.7 centigrade. It is soluble in water and insoluble in ethanol and carbon bisulfide, its aqueous solution shows alkaline and harms to skin. Heat it up to 100 centigrade, loses 11 crystal waters and becomes sodium phosphate monohydrate. Keep on heating up to 212 centigrade, it becomes sodium phosphate anhydrous . It is easy to airslake in the dry air.
