Tungsten hexacarbonyl Usage And Synthesis
ReactionVolatile starting material used for the atomic layer deposition of tungsten oxide, tungsten nitride.
Tungsten hexacarbonyl is used to produce tungsten coatings on base metals. This is done by deposition of the carbonyl on the metal surface, which decomposes to leave a tungsten coating.
PreparationTungsten hexacarbonyl is produced by heating tungsten metal with carbon monoxide at high pressure. Also, carbonyl can be prepared by reducing the tungsten hexachloride by heating with iron powder under carbon monoxide pressure.
Chemical PropertiesWhite, volatile, highly refractive, crystalline solid. Decomposes without melting at 150C. One of the more stable carbonyls. Insoluble in water; soluble in organic solvents.
UsesTungsten coatings on base metals by deposition and decomposition of the carbonyl.
UsesIt is used as a catalyst in many organicsynthetic reactions.
Health HazardToxicity of this compound is not reported.Although air stable at ambient temperature,upon heating it emits toxic carbonmonoxide. Chronic exposure to its vaporsor dusts can cause bronchitis. Ingestion islikely to produce the toxic effect of tungstenoxides.
Fire HazardIt explodes when heated to high temperature. Solution in ether can explode if stored for a long time.
Purification MethodsSublime it in vacuo before use [Connoe et al. J Chem Soc, Dalton Trans 511 1986]. TOXIC.
