Beschreibung

Nickel carbonyl is a clear colourless to yellow volatile liquid, is flammable, and burns with a yellow flame. It is denser than water and insoluble in water but soluble in alcohol, benzene, chloroform, acetone, ethanol, carbon tetrachloride, and nitric acid. The vapours are heavier than air. In industries, nickel carbonyl is used in nickel coat steel and other metals and to make very pure nickel. Nickel carbonyl gets peroxidised by air as a solid deposit and decomposes to ignite.

Chemische Eigenschaften

Nickel carbonyl is a colorless, highly volatile, flammable liquid with a musty odor. The Odor Threshold is 1.3 ppm. It decomposes above room temperature producing carbon monoxide and finely divided nickel.

Chemische Eigenschaften

colourless liquid with a musty odour

Verwenden

In organic synthesis; production of high-purity nickel powder and continuous nickel coatings on steel and other metals.

Verwenden

Nickel tetracarbonyl is used in the manufactureof nickel powder and nickel-coatedmetals, and as a catalyst in carboxylation,coupling, and cyclization reactions. It canform from the contact of carbon monoxidewith nickel.

Definition

nickel carbonyl: A colourlessvolatile liquid, Ni(CO)4; m.p.-25°C;b.p. 43°C. It is formed by direct combinationof nickel metal with carbonmonoxide at 50–60°C. The reaction isreversed at higher temperatures, andthe reactions are the basis of theMond process for purifying nickel.The nickel in the compound has anoxidation state of zero, and the compoundis a typical example of a complexwith pi-bonding ligands, inwhich filled d-orbitals on the nickeloverlap with empty p-orbitals on thecarbon.

Definition

A zero-valent compound. The four carbonyl groups form a tetrahedral arrangement and are linked covalently to the metal through the carbons

Allgemeine Beschreibung

A clear colorless to yellow liquid. Boiling point 43°C. Flash point below 0°F. Very toxic by ingestion and inhalation. Carcinogenic. Denser than water and insoluble in water. Vapors heavier than air. Used to nickel coat steel and other metals and to make very pure nickel.

Air & Water Reaktionen

Highly flammable over a wide range of vapor-air concentrations. Is peroxidized by air to give a solid deposit that tends to decompose and ignite. Insoluble in water.

Reaktivität anzeigen

NICKEL CARBONYL is easily oxidized. Presents a very serious fire hazard if exposed to heat, flame, sparks, oxidizing agents. Explodes when heated to about 60°C. Reacts explosively with bromine (liquid), oxygen in the presence of mercury, or hydrocarbons (butane) mixed with oxygen. Undergoes violent reactions with air, oxygen, dinitrogen tetraoxide. Caused an explosion when added to an n-butane-oxygen at 20-40°C [J. Am. Chem. Soc. 70:2055-6. 1948]. Reacts with tetrachloropropadiene to form an extremely explosive dinickel chloride dimer. Emits highly toxic fumes of carbon monoxide when heated to decomposition or in contact with mineral acids or acid fumes [Bretherick, 5th ed., 1995, p. 1734]. Vapor explodes in air or oxygen at 20°C and a partial pressure of 15 mm.

Hazard

Flammable, dangerous fire risk, explodes at 60C (140F). A lung irritant and confirmed carcinogen.

Health Hazard

Nickel tetracarbonyl is an extremely toxicsubstance by all routes of exposure exhibitingboth immediate and delayed effects. Thedelayed effects may manifest in a few hoursto days after exposure. Exposure to its vaporscan cause dizziness, giddiness, headache,weakness, and increased body temperature.Vapors are irritating to eyes, nose, andthroat. Prolonged exposure or inhalation ofits vapors at a further increased level ofconcentration may produce rapid breathing,followed by congestion of the lungs. Therespiration will initially be rapid with nonproductivecough, progressing to pain andtightness in the chest (U.S. EPA 1995). Highexposure can cause convulsion, hemorrhage,and death. Other symptoms from inhalationof vapors or ingestion of the liquid includehallucinations, delirium, nausea, vomiting,diarrhea, and liver and brain injury.
In humans, a 30-minute exposure to a 30-ppm concentration in air could be fatal. Afew whiffs of the vapors of the liquid cancause death. One minute exposure to 3000ppm of its vapor can cause death in humansfrom respiratory failure and acute pulmonaryedema. Similarly, swallowing 5–10 mL ofthe liquid can be fatal.
Nickel tetracarbonyl can be absorbedthrough the skin. While the skin contact witha dilute solution can cause dermatitis anditching, that from a concentrated solution orthe pure liquid can produce a burn. Absorptionof the liquid through the skin may resultin death. The subcutaneous and intravenousLD50 values in rats are 60–70 mg/kg.
LC50 (mouse): 0.067 mg/L/30 min (RTECS2004)
Evidence of carcinogenicity observed inexperimental animals dosed with nickel tetracarbonyl is limited. It caused tumors inthe lungs and liver. The compound is alsoteratogenic, causing birth defects.

Health Hazard

The acute toxicity of nickel carbonyl by inhalation is high. Acute toxic effects occur in two stages, immediate and delayed. Headache, dizziness, shortness of breath, vomiting, and nausea are the initial symptoms of overexposure; the delayed effects (10 to 36 h) consist of chest pain, coughing, shortness of breath, bluish discoloration of the skin, and in severe cases, delirium, convulsions, and death. Recovery is protracted and characterized by fatigue on slight exertion. Nickel carbonyl is not regarded as having adequate warning properties.
Repeated or prolonged exposure to nickel carbonyl has been associated with an increased incidence of cancer of the lungs and sinuses. Nickel carbonyl is listed by IARC in Group 2B ("possible human carcinogen"), is listed by NTP as "reasonably anticipated to be a carcinogen," and is classified as a "select carcinogen'' under the criteria of the OSHA Laboratory Standard.

Health Hazard

Probable oral lethal dose for a human is between 50 and 500 mg/kg, between one teaspoon and one ounce per 150 lb. person. NICKEL CARBONYL has also been estimated to be lethal in man at atmospheric exposures of 30 ppm for 20 minutes. Autopsies show congestion, collapse, and tissue destruction, as well as hemorrhage in the brain. Dermatitis, recurrent asthmatic attacks, and increased number of white blood cells (eosinophils) in respiratory tract are acute health hazards. NICKEL CARBONYL is poisonous. It can be fatal if inhaled, swallowed, or absorbed through skin. Vapors may cause irritation, congestion, and edema of lungs.

Brandgefahr

Vapor forms explosive mixtures with air. Vapor is heavier than air and may travel a considerable distance to source of ignition and flash back. Liquid may explode when heated under confinement. Vapor explosion and poison hazard indoors, outdoors, or in sewers. Runoff to sewer may create fire and explosion. May explode at 68F in presence of air or oxygen. Avoid contact with heat, acid or acid fumes as these cause the emission of highly toxic fumes. Avoid contact with air, ignition sources and vapors entering a confined space.

Brandgefahr

Nickel carbonyl is a highly flammable liquid (NFPA rating = 3) that may ignite spontaneously and explodes when heated above 60℃. Its lower flammable limit in air is 2% by volume; the upper limit has not been reported. Carbon dioxide, water, or dry chemical extinguishers should be used for nickel carbonyl fires.

Flammability and Explosibility

Nickel carbonyl is a highly flammable liquid (NFPA rating = 3) that may ignite spontaneously and explodes when heated above 60 °C. Its lower flammable limit in air is 2% by volume; the upper limit has not been reported. Carbon dioxide, water, or dry chemical extinguishers should be used for nickel carbonyl fires.

Sicherheitsprofil

ConfEmed carcinogen with experimental carcinogenic, tumorigenic, and teratogenic data. A human poison by inhalation. Poison experimentally by inhalation, intravenous, subcutaneous, and intraperitoneal routes. An experimental teratogen. Other experimental reproductive effects. Human systemic effects by inhalation: somnolence, fever, and other pulmonary changes. Vapors may cause coughing, dyspnea (difficult breathing), irritation, congestion and edema of the lungs, tachycardia (rapid pulse), cyanosis, headache, dizziness, and weakness. Toxicity by inhalation is believed to be caused by both the nickel and carbon monoxide liberated in the lungs. Chronic exposure may cause cancer of lungs, nasal sinuses. Sensitization dermatitis is fairly common. Probably the most hazardous compound of nickel in the workplace. A common air contaminant. It is lipid soluble and can cross biological membranes (e.g., lung alveolus, blood-brain barrier, placental barrier). A very dangerous fire hazard when exposed to heat, flame, or oxidizers. Moderate explosion hazard when exposed to heat or flame. Explodes when heated to about 60°. Explosive reaction with liquid bromine, mercury + oxygen, oxygen + butane. Violent reaction with dinitrogen tetraoxide, air, oxygen. Reacts with tetrachloropropadtene to form the extremely sensitive explosive dicarbonyl trichloropropenyl dinickel chloride dimer. Can react with oxidzing materials. To fight fire, use water, foam, CO2, dry chemical. When heated to decomposition or on contact with acid or acid fumes, it emits highly toxic fumes of carbon monoxide. See also NICKEL COMPOUNDS and CARBONYLS.

mögliche Exposition

Nickel carbonyl is used as an intermediate product in the refining of nickel. The primary use for nickel carbonyl is in the production of nickel by the Mond process. Impure nickel powder is reacted with carbon monoxide to form gaseous nickel carbonyl which is then treated to deposit high purity metallic nickel and release carbon monoxide. Other uses include gas plating; the production of nickel products; in chemical synthesis as a catalyst, particularly for oxo reactions (addition reaction of hydrogen and carbon monoxide with unsaturated hydrocarbons to form oxygen-function compounds); e.g., synthesis of acrylic esters; and as a reactant.

Lager

Work with nickel carbonyl should be conducted in a fume hood to prevent exposure by inhalation and splash goggles and impermeable gloves should be worn at all times to prevent eye and skin contact. Nickel carbonyl should only be used in areas free of ignition sources. Containers of nickel carbonyl should be stored in secondary containers in the dark in areas separate from oxidizers.

Versand/Shipping

UN1259 Nickel carbonyl, Hazard Class: 6.1; Labels: 6.1-Poisonous materials, 3-Flammable liquid, Inhalation Hazard Zone A. A United States DOT Severe Marine Pollutant.

Inkompatibilitäten

May spontaneously ignite on contact with air. In the presence of air, oxidizes and forms a deposit which becomes peroxidized; this tends to decompose and ignite. May explode when heated above 60 C. Decomposes on contact with acids producing carbon monoxide. Violent reaction with oxidizers; may cause fire and explosions. Vapor may promote the ignition of mixtures of combustible vapors (such as gasoline) and air. Attacks some plastics, rubber and coatings. Store under inert gas blanket.

Waste disposal

Incineration in admixture with a flammable solvent. Also, nickel carbonyl used in metallizing operations may be recovered and recycled. Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform with EPA regulations governing storage, transportation, treatment, and waste disposal.
