Procedure

For example, by dissolving sodium tungstate (VI) in distilled water, adding an aqueous solution of phosphoric acid to the obtained solution, and then adding concentrated sulfuric acid to adjust the pH to an acidic range, followed by addition of hydrogen peroxide, stirring at room temperature, and then, adding a halogenated quaternary ammonium such as tetra-(n-butyl)ammonium chloride, it is possible to obtain the tungstophosphoric acid salt represented by the formula (3) such as tri[tetra-(n-butyl)ammonium]tetra(diperoxotungsto)phosphoric acid salt.
