코발트 하이드로카보닐 화학적 특성, 용도, 생산

• 화학적 성질

  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,

• 용도

  Catalyst.

• 일반 설명

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

• 공기와 물의 반응

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

• 반응 프로필

  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.

• 위험도

  Flammable gas. Possible carcinogen.

• 건강위험

  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).

• 화재위험

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

• Safety Profile

  Poison by inhalation. See also COBALT COMPOUNDS.

• 잠재적 노출

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

• 운송 방법

  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.

• 비 호환성

  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

• 폐기물 처리

  Return refillable compressed gas cylinders to supplier.
