基本信息
| 应用 | Catalyst for organic synthesis, minerals separation, reagent for alkaloids.Tungstosilicic acid hydrate is used to prepare ethylacetate and acetic acid from ethylene. It is used in the preparation of silicotungstate butylmethylimidazolium bromide and charge transfer compounds with Keggin anions. It is also used in catalyst preparation, which is useful for catalytic liquid-phase oxidation of xylene. Further, it acts as a mediator in production of hydrogen through electrolysis of water. |
| 备注 | Strongly hygroscopic. Incompatible with strong oxidizing agents. |
