헥사카보닐 텅스텐 C화학적 특성, 용도, 생산
화학적 성질
White, volatile, highly refractive, crystalline solid. Decomposes without melting at 150C. One of the more stable carbonyls. Insoluble in water; soluble in organic solvents.물리적 성질
White crystalline solid; density 2.65 g/cm3; decomposes at 170°C without melting; sublimes; vapor pressure 0.1 torr at 20°C; insoluble in water; soluble in most organic solvents.용도
Tungsten Hexacarbonyl is an useful catalyst in carbonyation amines, as well as an stable source of tungsten atoms through electron beam-induced depostion.일반 설명
Atomic number of base material: 74 Tungsten건강위험
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.화재위험
It explodes when heated to high temperature. Solution in ether can explode if stored for a long time.Purification Methods
