| [Uses]
Reactant for Preparation of silicotungstate butylmethylimidazolium bromide ionic liquid hybrid material, Synthesis of SnII-substituted Keggin-type polyoxometalates as photocatalysts, Preparation of silicotungstic acid/organically modified silane proton-conducting membranes3, Preparation of charge transfer compounds with Keggin anions, Preparation of catalyst for catalytic liquid-phase oxidation of xylene | [Purification Methods]
Extract the acid with diethyl ether from a solution acidified with HCl. The diethyl ether is evaporated under vacuum, and the free acid is crystallised twice [Matijevic & Kerker J Phys Chem 62 1271 1958]. |
