Phosphotungstic Acid Hydrate

Phosphotungstic acid hydrate is a colorless, off-white powdery solid or pale yellow fine crystal. Its physical properties are as follows: chemical formula: H3O4OPW12.XH2O, molecular weight: 2880.05, Solubility: soluble in alcohol, ether and water, and related systems registry number: CAS: 12501-23-4, EINECS: 235-087-6. Because H3O4OPW12.XH2O absorbs moisture easily, so it should be sealed storage in a cool, dry place. In addition, phosphotungstic acid hydrate has slight weathering, but also it has acidic and redox properties, so it is a versatile new catalyst.
Phosphotungstic acid hydrate usually  used as a catalyst, biochemical reagents and chromatography reagents, biological staining and a variety of alkaloids, a nitrogenous base, phenol, protein, peptone, amino acids, uric acid, urea, blood and carbohydrate reagents. H3O4OPW12.XH2O as a catalyst to get the attention of people mainly that it should have a high catalytic activity, good stability, can be used for homogeneous and heterogeneous reactions, and even can be used as a phase transfer catalyst. What’s more, it is pollution-free and green catalyst.
