Description

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. This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
