CARBON MONOXIDE Usage And Synthesis
Chemical PropertiesCarbon monoxide, CO,is a colorless,odorless, toxic gas.It is soluble in alcohol and cuprix chloride solutions, but insoluble in water. Carbon monoxide is formed by the incomplete oxidation of carbon. It is found in mines and carexhaust. Carbon monoxide is used in metallurgy as a reducing agent in smelting operations, in the production of carbony is for the separation of various metals, as an ingredient in the synthesis of phosgene,and as an intermediate in the production of methanol.
Chemical PropertiesCarbon monoxide (CO) is a colorless, odorless, tasteless gas that is extremely hazardous. CO can be formed from incomplete burning of gasoline, wood, kerosene, or other fuels. CO is also found in cigarette smoke and vehicle exhaust. In homes, CO can build up from a poorly vented or malfunctioning heater, furnace, range, or any appliance that runs on natural gas or oil. The presence of CO is very common inside and outside workplaces, around heaters: improper use of gas or kerosene-fi red heaters, gas-fi red central heating equipment combined with improper venting or chimney, due to blocked heating fl ues, improper fl ue vent connector, or hood installation, inadequate combustion air, from exhaust, and gas-fi red water heaters.
Chemical PropertiesCarbon monoxide is a flammable, colorless, odorless, tasteless gas, partially soluble in water.
UsesAs reducing agent in metallurgical operations especially in the Mond process for the recovery of nickel; in organic synthesis especially in the Fischer-Tropsch processes for petroleum-type products and in the oxo reaction; in the manufacture of metal carbonyls.
General DescriptionA colorless cryogenic liquid. Prolonged exposure to carbon monoxide rich atmospheres may be fatal. Contact with the liquid can cause severe frostbite. Less dense than air. Easily ignited and a flame can flash back to the source of a leak very easily. Burns with a violet flame. Under prolonged exposure to fire or intense heat the containers may rupture violently and rocket. CARBON MONOXIDE is used in organic synthesis, metallurgy, and a fuel.
Air & Water ReactionsHighly flammable.
Reactivity ProfileContact of very cold liquefied gas with water may result in vigorous or violent boiling and extremely rapid vaporization. If the water is hot, a liquid "superheat" explosion may occur. Pressures may build to dangerous levels if the liquid contacts water in a closed container [Handling Chemicals Safely 1980]. Reacts explosively with bromine trifluoride at high temperatures or concentrations [Mellor 2, Supp. 1:166 1956]. The same is true for various oxidizers such as: chlorine dioxide, oxygen (liquid), peroxodisulfuryl difluoride. Reacts with lithium to give lithium carbonyl, which detonates violently with water, igniting the gaseous products [Mellor 2, Supp 2:84 1961]. Potassium and sodium metals behave similarly. Cesium oxide, iron(III) oxide, and silver oxide all react, in the presence of moisture, at ambient temperatures with carbon monoxide causing ignition, [Mellor, 1941, vol. 2, 487].
HazardHighly flammable, dangerous fire and explosion risk. Flammable limits in air 12–75% by volume. Toxic by inhalation. Note: Carbon monox- ide has an affinity for blood hemoglobin over 200 times that of oxygen. A major air pollutant.
Health HazardTOXIC; Extremely Hazardous. Inhalation extremely dangerous; may be fatal. Contact with gas or liquefied gas may cause burns, severe injury and/or frostbite. Odorless, will not be detected by sense of smell.
Health HazardCO is a highly toxic gas often called a chemical asphyxiant. When inhaled, it combines with hemoglobin more readily than oxygen does, displacing oxygen from hemoglobin, thereby interfering with oxygen transport by the blood. The early symptoms of CO poisoning include, headaches, nausea, and fatigue, which are often mistaken for the fl u because CO is not detected in the home. Prolonged exposure to CO causes deleterious health effects, brain damage, and eventually death. CO poisoning can happen to anyone, anytime, almost anywhere. CO poisoning is often confused with the fl u. Depending on the period of exposure and concentration of CO, poisoning may be severe, moderate, or mild. (i) Extreme exposures cause confusion, drowsiness, rapid breathing or pulse rate, vision problems, chest pain, convulsions, seizures, loss of consciousness, cardiorespiratory failure, and death. (ii) Moderate exposures cause severe throbbing headache, drowsiness, confusion, vomiting, and fast heart rate. (iii) Mild exposures cause slight headache, nausea, fatigue (often described as “fl u-like” symptoms). The symptoms of CO poisoning include, but are not limited to, drowsiness, nausea, tiredness, vomiting, headaches, dizziness, visual changes, abdominal pain, chest pains, memory and walking problems, brain damage and, in severe cases, death. Exposure to high concentrations of CO causes severe headache, weakness, dizziness, irregular heart beat, seizures, coma, respiratory failure, and unconsciousness. The toxicity of CO results from its very tight binding to hemoglobin, the species that carries oxygen from the lungs to the bodily tissues. For hemoglobin to work, it can’t bind oxygen very tightly (otherwise it couldn’t release it at its destination). Unfortunately, CO
Health HazardThe acute toxicity of carbon monoxide by inhalation is moderate. Carbon monoxide is a chemical asphyxiant that exerts its effects by combining preferentially with hemoglobin, the oxygen-transport pigment of the blood, thereby excluding oxygen. Symptoms of exposure to CO at 500 to 1000 ppm include headache, palpitations, dizziness, weakness, confusion, and nausea. Loss of consciousness and death may result from exposure to concentrations of 4000 ppm and higher; high concentrations may be rapidly fatal without producing significant warning symptoms. Exposure to this gas may aggravate heart and artery disease and may cause chest pain in individuals with preexisting heart disease. Pregnant women are more susceptible to the effects of carbon monoxide exposure. Since carbon monoxide is odorless, colorless, and tasteless, it has no warning properties, and unanticipated overexposure to this highly dangerous gas can readily occur. Carbon monoxide has not been found to be carcinogenic in humans. This substance has shown developmental toxicity in animal tests. Chronic exposures to carbon monoxide at levels around 50 ppm are thought by some investigators to have a negative impact on the results of behavioral tests such as time discrimination, visual vigilance, choice response tests, visual evoked responses, and visual discrimination thresholds.
Fire HazardEXTREMELY FLAMMABLE. May be ignited by heat, sparks or flames. Flame may be invisible. Containers may explode when heated. Vapor explosion and poison hazard indoors, outdoors or in sewers. Vapors from liquefied gas are initially heavier than air and spread along ground. Vapors may travel to source of ignition and flash back. Runoff may create fire or explosion hazard.
Fire HazardCarbon monoxide is a flammable gas. It forms explosive mixtures with air in the range of 12.5 to 74% by volume.
Safety ProfileMddly toxic by inhalation in humans but has caused many fatalities. Experimental teratogenic and reproductive effects. Human systemic effects by inhalation: changes in psychophysiological tests and methemoglobinemiacarboxyhemoglobinemia. Can cause asphyxiation by preventing hemoglobin from bindmg oxygen. After removal from exposure, the half-life of elimination from the blood is one hour. Chronic exposure effects can occur at lower concentrations. A common air contaminant. Acute cases of poisoning resulting from brief exposures to hgh concentrations seldom result in any permanent dtsability if recovery takes place. Chronic effects as the result of repeated exposure to lower concentrations have been described, particularly in the Scandinavian literature. Auditory disturbances and contraction of the visual fields have been demonstrated. Glycosuria does occur, and heart irregularities have been reported. Other workers have found that where the poisoning has been relatively long and severe, cerebral congestion and edema may occur, resulting in long-lasting mental or nervous damage. Repeated exposure to low concentration of the gas, up to 100 ppm in air, is generally believed to cause no signs of poisoning or permanent damage. Industrially, sequelae are rare, as exposure, though often severe, is usually brief. It is a common air contaminant. flame. Severe explosion hazard when exposed to heat or flame. Violent or explosive reaction on contact with bromine trifluoride, bromine pentafluoride, chlorine doxide, or peroxodsulfuryl difluoride. Mixture of liquid CO with liquid O2 is explosive. Reacts with sodurn or potassium to form explosive products sensitive to shock, heat, or contact with water. Murture , , . with copper powder + copper(Ⅱ) perchlorate + water forms an explosive complex. dime of liquid CO with liquid dinitrogen oxide is a rocket propellant combination. Ignites on warming with iodine heptafluoride. Ignites on contact with . cesium oxide + water. Potentially explosive reaction with iron(IⅡ) oxide between 0' and 150℃. Exothermic reaction with CIF3, (Li + H2O), NF3,OF2, (K + 04, Ag2O, (Na + NH3). To fight fire, stop flow of gas. A dangerous fire hazard when exposed to
Potential ExposureCarbon monoxide is used in metallurgy as a reducing agent, particularly in the Mond process for nickel; in organic synthesis, especially in the FischerTropsch process for petroleum products, and in the oxo reaction; and in the manufacture of metal carbonyls. It is usually encountered in industry as a waste product of incomplete combustion of carbonaceous material (complete combustion produces CO2). The major source of CO emission in the atmosphere is the gasoline-powered internal combustion engine. Special industrial processes which contribute significantly to CO emission are iron foundries, particularly the cupola; fluid catalytic crackers; fluid coking; and moving-bed catalytic crackers in thermal operations in carbon black plants; beehive coke ovens; basic oxygen furnaces, sintering of blast furnace feed in steel mills; and formaldehyde manufacture. There are numerous other operations in which a flame touches a surface that is cooler than the ignition temperature of the gaseous part of the flame where exposure to CO may occur,e.g., arc welding, automobile repair; traffic control; tunnel construction; firefighting; mines, use of explosives, etc.

storagecylinders of carbon monoxide should be stored and used in a continuously ventilated gas cabinet or fume hood. Local fire codes should be reviewed for limitations on quantity and storage requirements.
ShippingUN1016 Carbon monoxide, compressed, Hazard class: 2.3; Labels: 2.3-Poisonous gas; 2.1- Flammable gas, Inhalation Hazard Zone D. NA9202 Carbon monoxide, refrigerated liquid (cryogenic liquid), Hazard class: 2.3; Labels: 2.3-Poisonous gas; 2.1- Flammable gas, Domestic (United States), Inhalation Hazard Zone D. Cylinders must be transported in a secureupright 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.
Purification MethodsIron carbonyl is a likely impurity in CO stored under pressure in steel tanks. It can be decomposed by passing the gas through a hot porcelain tube at 350-400o. Passage through alkaline pyrogallol solution removes oxygen (and CO2). Removal of CO2 and water are effected by passage through soda-lime followed by Mg(ClO4)2 or P2O5 and collected over Hg. Carbon monoxide can be condensed and distilled at -195o. It is sparingly soluble in H2O but is readily absorbed by a solution of CuCl in HCl to give the white crystalline adduct CuCl.CO.2H2O. It burns in air with a bright blue flame but a mixture of 2volumes of CO and 1volume of O2 explode when kindled, although in a small jar the combustion is not violent. HIGHLY POISONOUS gas as it reacts with haemoglobin to form bright red carboxyhaemoglobin which is stable and not readily decomposed by oxygen. [Gilliland & Blanchard Inorg Synth II 81 1946, Glemser in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol I p 645-646 1963.]
Flammability and ExplosibilityCarbon monoxide is a flammable gas. It forms explosive mixtures with air in the range of 12.5 to 74% by volume.
IncompatibilitiesForms extremely explosive mixture with air. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. In the presence of finely dispersed metal powders the substance forms toxic and flammable carbonyls. May react vigorously with oxygen, acetylene, chlorine, fluorine, nitrous oxide.
Waste DisposalReturn refillable compressed gas cylinders to supplier. Dissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All federal, state, and local environmental regulations must be observed. Carbon monoxide can also be recovered from gas mixtures as an alternative to disposal.
PrecautionsCarbon monoxide poisoning, prevention, occupational safety Install a CO alarm on each level of your home. Home heating systems, chimneys, and fl ues must be inspected and cleaned by a qualifi ed technician every year. Keep chimneys clear of bird and squirrel nests, leaves, and residue to ensure proper ventilation. Make sure that the furnace and other appliances, such as gas ovens, ranges, and cooktops are inspected for adequate ventilation. Do not burn charcoal inside the house even in the fi replace. Do not operate gasoline-powered engines in confi ned areas, such as garages or basements. Do not leave your car, mower, or other vehicle running in an attached garage, even with the door open. Do not block or seal shut exhaust fl ues or ducts for appliances such as water heaters, ranges, and clothes dryers.
