コバルトヒドロカルボニル 化学特性,用途語,生産方法

• 化学的特性

  Cobalt hydrocarbonyl is an unstable, highly flammable and toxic gas or liquid which decomposes rapidly at room temperature to toxic cobalt carbonyl. It has an offensive odor,

• 使用

  Catalyst.

• 一般的な説明

  Gas with an offensive odor. Mp: -26°C

• 空気と水の反応

  Air [Note: Unstable gas that decomposes rapidly in air at room temperature to cobalt carbonyl & hydrogen.]

• 反応プロフィール

  COBALT HYDROCARBONYL is flammable. Reacts exothermically with strong oxidizing agents and acids. Decomposes rapidly in air at room temperature to cobalt carbonyl (an orange solid of formula Co(CO)4) and hydrogen. These products also act as reducing agents. The orange solid (cobalt carbonyl) decomposes at 52°C producing toxic fumes of carbon monoxide and cobalt; reacts with acids and strong oxidizing agents below that temperature.

• 危険性

  Flammable gas. Possible carcinogen.

• 健康ハザード

  The toxic effects are similar to those ofnickel tetracarbonyl or iron pentacarbonyl.The acute toxicity, however, is lower thanthat of these two carbonyls. Inhalation ofthe gas can cause dizziness, giddiness, andheadache. It readily decomposes at roomtemperature producing toxic carbon monoxide.A 30-minute LC50 in rats is 165 mg/m³(Palmes et al. 1959).

• 火災危険

  Flammable gas; the liquid form can explode when heated in a closed container due to rapid decomposition and heavy pressure buildup.

• 安全性プロファイル

  Poison by inhalation. See also COBALT COMPOUNDS.

• 職業ばく露

  A potential danger to those involved in manufacture and use of this material as a catalyst for organic reactions.

• 輸送方法

  UN3281 Metal carbonyls, liquid, n.o.s., Hazard class: 6.1; Labels: 6.1 Technical Name Required, Potential Inhalation Hazard (Special Provision 5). Cylinders must be transported in a secure upright position, in a well-ventilated truck. Protect cylinder and labels from physical damage. The owner of the compressed gas cylinder is the only entity allowed by federal law (49CFR) to transport and refill them. It is a violation of transportation regulations to refill compressed gas cylinders without the express written permission of the owner. UN2927 Toxic liquids, corrosive, organic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, 8-Corrosive material, Technical Name Required.

• 不和合性

  Unstable gas; decomposes rapidly in air at room temperature to toxic cobalt carbonyl and explosive hydrogen gas. A strong metal hydride reducing agent; violent reaction with oxidizers and acids. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Aqueous solution is highly acidic. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides

• 廃棄物の処理

  Return refillable compressed gas cylinders to supplier.
