organic solvents.
物理的性質
White crystalline solid; density 2.65 g/cm
3; decomposes at 170°C without melting; sublimes; vapor pressure 0.1 torr at 20°C; insoluble in water; soluble in most organic solvents.
使用
Tungsten Hexacarbonyl is an useful catalyst in carbonyation amines, as well as an stable source of tungsten atoms through electron beam-induced depostion.
一般的な説明
Atomic number of base material: 74 Tungsten
健康ハザード
Toxicity 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.
火災危険
It explodes when heated to high temperature.
Solution in ether can explode if stored for a
long time.
純化方法
Sublime it in vacuo before use [Connoe et al. J Chem Soc, Dalton Trans 511 1986]. TOXIC.
