| TUNGSTEN(VI) CHLORIDE Usage And Synthesis |
Chemical Properties | dark grey-violet crystalline powder | Uses | Precursor to tungsten-based carbenes which catalyze the olefin metathesis reactions of 1- and 2-octene. | Uses | A precursor to tungsten based carbenes. | Uses | It is a precursor for many tungsten compounds. It is used in tungsten plating, purification of tungsten, and olefin polymerization. It is also used as petroleum catalyst, and in intelligent glass. It can be used for deoxygenation of epoxides and as a reagent in organic synthesis. | Definition | ChEBI: Tungsten hexachloride is a tungsten coordination entity. | Flammability and Explosibility | Notclassified | Purification Methods | Sublime it in a stream of Cl2 in a high temperature furnace and collect it in a receiver cooled in a Dry Ice-acetone bath in an inert atmosphere because it is sensitive to moisture. It is soluble in CS2, CCl4, CHCl3, POCl3, *C6H6, pet ether and Me2CO. Its solutions decompose on standing. Good crystals can be obtained by heating WCl6 in CCl4 to 100o in a sealed tube, followed by slow cooling (tablets of four-sided prisms). Store it in a desiccator over H2SO4 in the dark.
