Chromium hexacarbonyl Usage And Synthesis
Reaction    
Reagent for the preparation of Fischer carbenes.
Reagent for the preparation of arenechromium complexes.

Description    Chromium carbonyl is a colorless crystallinesubstance which sinters (forms a coherent mass withoutmelting) at 90℃. Molecular weight =220.06; Freezing/Melting point =110℃ (decomposes). Boilingpoint 5 explodes (in lieu of boiling) at 210℃. HazardIdentification (based on NFPA-704 M Rating System):Health 2, Flammability 1, Reactivity 0. Insoluble in water;possible reaction.
Chemical Properties    white crystals or powder
Chemical Properties    Chromium carbonyl is a colorless crystalline substance which sinters (forms a coherent mass without melting) @ 90°C.
Physical properties    White orthogonal crystal; density 1.77 g/cm3; sublimes at ordinary temperatures; vapor pressure 1 torr at 48°C; decomposes at 130°C; insoluble in water and alcohols; soluble in ether, chloroform and methylene chloride.
Uses    Chromiumhexacarbonyl is a volatile; air stable precursor of Chromium(0); widely used for thin film deposition - ALD and CVD. The thin films can be grown at room temperature and low pressure by laser CVD .
Uses    In catalysts for olefin polymerization and isomerization; gasoline additive to increase octane number; preparation of chromous oxide, CrO.
Uses    It is used as a catalyst for polymerization andisomerization of olefins. It is also used as anadditive to gasoline, to increase the octanenumber.
Preparation    Chromium hexacarbonyl is prepared by the reaction of anhydrous chromium(III) chloride with carbon monoxide in the presence of a Grignard reagent. A 60% product yield may be obtained at the carbon monoxide pressures of 35 to 70 atm. Other chromium salts may be used with carbon monoxide and Grignard reagent in the preparation. The compound may also be obtained by the reaction of a chromium salt with carbon monoxide in the presence of magnesium in ether or sodium in diglyme.
General Description    White crystalline or granular solid. Sublimes at room temperature. Burns with a luminous flame.
Air & Water Reactions    Insoluble in water.
Reactivity Profile    Chromium hexacarbonyl decomposes violently at 410° F. Chromium hexacarbonyl is decomposed by chlorine and fuming nitric acid. Chromium hexacarbonyl is incompatible with oxidizing agents.
Hazard    Toxic by inhalation and ingestion.
Health Hazard    Chromium hexacarbonyl is a highly toxicsubstance by all routes of exposure. The toxiceffects are similar to those of molybdenumand tungsten carbonyls. The symptoms areheadache, dizziness, nausea, vomiting, andfever. The oral LD50 in mice is 150 mg/kgand in rats 230 mg/kg. The intravenous LD50in mice is 30 mg/kg. As a hexavalent compoundof chromium, it is a carcinogenic substance.
Fire Hazard    Flash point data for Chromium hexacarbonyl are not available; however, Chromium hexacarbonyl is probably combustible.
reaction suitability    core: chromium
reagent type: catalyst
Potential Exposure    Chromium carbonyl is used as a catalyst for hydrogenation, isomerization, water
gas shift reaction and alkylation of aromatic hydrocarbons; gasoline additive to increase octane number; preparation of chromous oxide, CrO
First aid    Skin Contact: Flood all areas of body that havecontacted the substance with water. Do not wait to removecontaminated clothing; do it under the water stream. Usesoap to help assure removal. Isolate contaminated clothingwhen removed to prevent contact by others. Eye Contact:Remove any contact lenses at once. Immediately flush eyeswell with copious quantities of water or normal saline for atleast 2030 min. Seek medical attention. Inhalation: Leavecontaminated area immediately; breathe fresh air. Properrespiratory protection must be supplied to any rescuers. Ifcoughing, difficult breathing, or any other symptomsdevelop, seek medical attention at once, even if symptomsdevelop many hours after exposure. Ingestion: Contact aphysician, hospital, or poison center at once. If the victim isunconscious or convulsing, do not induce vomiting or giveanything by mouth. Assure that the patient’s airway is openand lay him on his side with his head lower than his bodyand transport immediately to a medical facility. If consciousand not convulsing, give a glass of water to dilute the substance. Vomiting should not be induced without a physician’s advice
