| Questions And Answer | Back Directory | [Carbon oxide compounds]
Carbon dioxide (CO2) is the 18th most frequently produced chemical in the United States. It has numerous uses, including in refrigeration, in the manufacture of carbonated drinks (e.g., soda pop), in fire extinguishers, in providing an inert atmosphere (unreactive environment), and as a moderator for some types of nuclear reactors.
Solid carbon dioxide is used quite extensively to refrigerate dairy products, meat products, frozen foods, and other perishable foods while in transit. It is also used as a cooling agent in many industrial processes, such as grinding heat-sensitive materials, rubber tumbling, cold-treating metals, shrink fitting of machinery parts, vacuum cold traps, and so on.
Gaseous carbon dioxide is used to carbonate soft drinks, for pH control in water treatment, in chemical processing, as a food preservative, as an inert blanket in chemical and food processing and metal welding, as a growth stimulant for plant life, for hardening molds and cores in foundries, and in pneumatic devices.
Liquid carbon dioxide is used as an expendable refrigerant for freezing and chilling food products; for low-temperature testing of aviation, missile, and electronic components; for stimulation of oil and gas wells; for rubber tumbling; and for controlling chemical reactions.
Liquid carbon dioxide is also used as a fire extinguishing agent in portable and built-in fire extinguishing systems. |
| Hazard Information | Back Directory | [Chemical Properties]
Carbon dioxide is a colorless, odorless, noncombustible gas. | [Chemical Properties]
Carbon dioxide,CO2, also known as carbonic anhydride and carbonic acid gas, is a colorless,odorless gas that liquifies at -65 °C(-86 OF) and solidifies in dry ice at -78.2 °C(-107 OF). It is soluble in water,alcohol, and most alkaline solutions. In a relatively slow reaction,carbon dioxide hydrates in water to become carbonic acid and is corrosive. In petroleum production, the velocity of the carbon dioxide gas can increase the corrosion rate to very high levels,with the presence of salts becoming unimportant. Carbon dioxide is used in preparing carbonated beverages, fire extinguishers, dry ice refrigerants,and as a raw material in the production of sodium carbonate and sodium bicarbonate using the Solvay procedure.
| [Definition]
ChEBI: A one-carbon compound with formula CO2 in which the carbon is attached to each oxygen atom by a double bond. A colourless, odourless gas under normal conditions, it is produced during respiration by all animals, fungi and microorganism
that depend directly or indirectly on living or decaying plants for food. | [General Description]
An odorless, white solid. Can cause damaging frostbite. Noncombustible and nontoxic. Liquefies at-109°F. Can asphyxiate by displacement of air. Used as a refrigerant. | [Reactivity Profile]
Contact of very cold liquid/solid carbon dioxide with water may result in vigorous or violent boiling of the product and extremely rapid vaporization due to the large temperature differences involved. If the water is hot, there is the possibility that a liquid "superheat" explosion may occur. Pressures may build to dangerous levels if liquid gas contacts water in a closed container. With water forms weak carbonic acid in nonhazardous reaction. Dusts of magnesium, lithium, potassium, sodium, zirconium, titanium, and some magnesium-aluminum alloys, and heated aluminum, chromium, and magnesium when suspended in carbon dioxide are ignitable and explosive. This is especially true in the presence of strong oxidizers, such as peroxides. The presence of carbon dioxide in solutions of aluminum hydride in ether can cause violent decomposition on warming the residue, [J. Amer. Chem. Soc., 1948, 70, 877]. Dangers arising from the use of carbon dioxide in the fire prevention and extinguishing systems of confined volumes of air and flammable vapors are examined. The hazard associated with its use centers around the fact that large electrostatic discharges may be created that initiate explosion, [Quart. Saf. Summ., 1973, 44(1740, 10]. | [Air & Water Reactions]
Water soluble. Forms carbonic acid, a mild acid in water. | [Hazard]
Solid damaging to skin and tissue; keep
away from mouth and eyes. Asphyxia.
| [Health Hazard]
Vapors may cause dizziness or asphyxiation without warning. Vapors from liquefied gas are initially heavier than air and spread along ground. Contact with gas or liquefied gas may cause burns, severe injury and/or frostbite. | [Potential Exposure]
Gaseous Carbon dioxide is used to
carbonate beverages; as a weak acid in the textile, leather,
and chemical industries; in water treatment; and in the
manufacture of aspirin and white lead; for hardening molds
in foundries; in food preservation, in purging tanks and
pipe lines; as a fire extinguisher, in foams; and in welding.
Because it is relatively inert, it is utilized as a pressure
medium. It is also used as a propellant in aerosols; to promote plant growth in green houses; it is used medically as
a respiratory stimulant; in the manufacture of carbonates;
and to produce an inert atmosphere when an explosive or
flammable hazard exists. The liquid is used in fire extinguishing equipment; in cylinders for inflating life rafts; in
the manufacturing of dry ice, and as a refrigerant. Dry ice
is used primarily as a refrigerant. Occupational exposure to
carbon dioxide may also occur in any place where fermentation processes may deplete oxygen with the formation of
carbon dioxide, e.g., in mines, silos, wells, vats, ships’
holds, etc. | [Fire Hazard]
Non-flammable gases. Containers may explode when heated. Ruptured cylinders may rocket. | [First aid]
If dry ice gets into the eyes, get medical attention. If this chemical contacts the skin, get medical attention for frostbite. If a person breathes in large amounts of
this chemical, move the exposed person to fresh air at oncend perform rescue breathing and CPR if heart action has

Carbon dioxide is found throughout nature. Its concentration in the air is 0.036% by volume. It is the primary component of exhaled air of all animals. It also is the product of oxidation of all carbonaceous matter and an end prod?uct of complete combustion. It also is found dissolved in natural waters. It occurs in the earth’s crust and in volcanic eruptions.
All plants depend on carbon dioxide and water for their survival, making their food by the process of photosynthesis. Carbon dioxide is found in abun?dance in the atmospheres of many other planets and their moons throughout the solar system.
Carbon dioxide is a greenhouse gas, which traps the infrared radiation re?radiated back by the earth’s surface, causing global warming and, therefore, changing the climate. The CO2 concentration in the atmosphere over a 30- year period from 1960 to 1990 has increased significantly from about 320 to 356 ppm by volume, which is widely attributed to the growth of industrial and automobile CO2 emission during this period.
Carbon dioxide has extensive commercial applications. Some important applications of this compound include carbonation of beverages; as a fire extinguishing agent; in the manufacture of carbonates; as dry ice (solid CO2) for refrigeration; as an aerosol propellant; as a shielding gas for welding; as an inert atmosphere in preparation and handling of flammable substances; in cloud seeding; in fumigation of rice; to produce harmless smoke on stage; as an antiseptic; and as a supercritical fluid to extract organic pollutants for their analyses. | [History]
The discovery of carbon dioxide, credited to Joseph Black (1728–1799), played a critical role in supplanting the phlogiston theory and advancing the development of modern chemistry. Black, in his medical studies, was searching for a substance to dissolve kidney stones, but he switched his subject to a study of stomach acidity. Black was working with the carbonates magnesia alba (magnesium carbonate) and calcium carbonate (limestone) and observed that when magnesia alba was heated or reacted with acids, it produced a gas and a salt. Black, who published his work in 1756, called the gas “fixed air” and noted that it had properties similar to those described by Jan Baptista van Helmont (1577–1644) for spiritus sylvestrius. Spiritus sylvestrius was the gas produced during combustion processes, and van Helmont realized that this was the same gas produced during fermentation and when acids reacted with seashells. | [Preparation]
Carbon dioxide is produced as a by-product in many processes. It is pro duced as a by-product in the manufacture of lime from calcium carbonate:
CaCO3 →CaO + CO2
CO2 also is derived from synthesis gas which is a mixture of CO, CO2, H2 and N2 from air obtained by steam reforming. Carbon dioxide also is obtained by combustion of natural gas:
CH4 + 2O2 → CO2 + 2H2O
It also is obtained as a by-product in the Haber-Bosch process for the man ufacture of ammonia. The method involves passing steam and air over hot coke.
Carbon dioxide also is produced along with ethanol from fermentation of carbohydrates by yeast:
C6H12O6→2CO2 + 2C2H5OH
In the laboratory, CO2 may be produced by the reaction of any carbonate with a dilute mineral acid:
CaCO3 + 2HCl → CaCl2 + CO2 + H2O
| [Production Methods]
Carbon dioxide accounts for 0.037% by volume of the atmosphere.Several methods can be used to produce large volumes of CO2. The combustion of coke or other carbonaceous substances produces results in CO2: C(coke) + O2 → CO2(g). In combustion processes, CO2 is concentrated by separating it from other gases using scrubbing and absorption techniques. Another source of CO2 involves the calcination (slow heating) of carbonates such as limestone, CaCO3: CaCO3(s)→ CaO + CO2(g).This process takes place in a lime kiln in the production of precipitated calcium carbonate at temperatures of from 500°C to 900°C. Carbon dioxide is also produced as a by-product in fermentation reactions to produce alcohols. An example is the fermentation of glucose, C6H12O6 to ethanol (C2H5OH): C6H12O6(aq)→ 2C2H5OH(aq) + 2CO2(g). Carbon dioxide is produced as a by-product in a number of syntheses, such as the Haber process, to produce ammonia. | [Production Methods]
Carbon dioxide is obtained industrially in large quantities as a byproduct
in the manufacture of lime; by the incineration of coke or
other carbonaceous material; and by the fermentation of glucose by
yeast. In the laboratory it may be prepared by dropping acid on a
carbonate. | [Purification Methods]
Pass the gas over CuO wire at 800o to oxidise CO and other reducing impurities (such as H2), then over copper dispersed on Kieselguhr at 180o to remove oxygen. Drying it at -78o removes the water vapour. Final purification is by vacuum distillation at liquid nitrogen temperature to remove non-condensable gases [Anderson et al. J Chem Soc 3498 1962]. Sulfur dioxide contaminant can be removed at 450o using silver wool combined with a plug of platinised quartz wool. Halogens are removed by using Mg, Zn or Cu, heated to 450o. [Glemsner in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol I p 647 1963.] | [Agricultural Uses]
Carbon dioxide (CO2) is a compound of two oxygen
atoms covalently bonded to a carbon atom. It is a
colorless, odorless, tasteless gas, soluble in water,
ethanol and acetone, and is 15 times heavier than air.
Carbon dioxide occurs in the earth's atmosphere at an
average of 0.04% by volume. The volume keeps changing,
as it is consumed by plants during photosynthesis and
replenished during respiration and combustion of
biomass. CO2 is a major source of carbon for plants.
Carbon dioxide is readily prepared in a laboratory by
the action of dilute acids on carbonates. It is also obtained
as a by-product from the manufacture of lime and from
fermentation processes. Chemically, CO2 is not reactive
and does not support combustion. It gives carbonic acid
on dissolution in water.
Carbon dioxide is one of the key materials for urea
production. Liquid carbon dioxide is produced at high
pressures and has a small liquid range. Solid carbon
dioxide (known as dry ice), produced by subjecting
gaseous carbon dioxide to pressure and temperature, is
used in refrigeration, carbonated drinks and fire
extinguishers. It is also a constituent of medical
treatment, as it promotes exhalation.
The level of carbon dioxide in the atmosphere has
increased by 12% in the last 100 years, mainly due to the
burning of fossil fuels and the destruction of rain forests.
The increased level of carbon dioxide is the main cause
for an average increase of 0.5℃ in the mean global
temperature through the greenhouse effect.
Environmentalists urge that measures be taken to prevent
any further increase in atmospheric carbon dioxide, and the
subsequent global warming and melting of ice caps.
In calcareous soils, the partial pressure of carbon
dioxide in the soil air influences its pH; it is 8.5 when free
calcium carbonate in the soil is in equilibrium with
atmospheric carbon dioxide. An increase in carbon
dioxide in the soil air decreases the pH to around 7.3.
Applications of carbon dioxide include its use as (a) a
refrigerant in either solid or liquid form, (b) an inert
medium, (c) a chemical reactant, (d) a neutralizing agent
for alkalis, (e) a pressurizing agent, and ( f ) an ingredient
in the manufacture of aerated water. | [Agricultural Uses]
Solid carbon dioxide is known as dry ice. It is produced by cooling gaseous carbon dioxide under pressure.
Dry ice is used in refrigeration, carbonated drinks and fire extinguishers. It is also a constituent of medical gases, as it promotes exhalation. | [Pharmaceutical Applications]
Carbon dioxide and other compressed gases such as nitrogen and
nitrous oxide are used as propellants for topical pharmaceutical
aerosols. They are also used in other aerosol products that work
satisfactorily with the coarse aerosol spray that is produced with
compressed gases, e.g. cosmetics, furniture polish, and window
cleaners.
The advantages of compressed gases as aerosol propellants are
that they are less expensive; are of low toxicity; and are practically
odorless and tasteless. Also, in comparison to liquefied gases, their
pressures change relatively little with temperature. However, the
disadvantages of compressed gases are that there is no reservoir of
propellant in the aerosol and pressure consequently decreases as the
product is used. This results in a change in spray characteristics.
Additionally, if a product that contains a compressed gas as a
propellant is actuated in an inverted position, the vapor phase,
rather than the liquid phase, is discharged. Most of the propellant is
contained in the vapor phase and therefore some of the propellant
will be lost and the spray characteristics will be altered. Also, sprays
produced using compressed gases are very wet. Valves, such as the
vapor tap or double dip tube, are currently available and will
overcome these problems.
Carbon dioxide is also used to displace air from pharmaceutical
products by sparging and hence to inhibit oxidation. As a food
additive it is used to carbonate beverages and to preserve foods such
as bread from spoilage by mold formation, the gas being injected
into the space between the product and its packaging.
Solid carbon dioxide is also widely used to refrigerate products
temporarily, while liquid carbon dioxide, which can be handled at
temperatures up to 318℃ under high pressure, is used as a solvent
for flavors and fragrances, primarily in the perfumery and food
manufacturing industries. | [Safety]
In formulations, carbon dioxide is generally regarded as an
essentially nontoxic material. | [Physiological effects]
Carbon dioxide is nonnally present in the atmosphere
at about 0.035 percent by volume. It
is also a nonnal end-product of human and animal
metabolism. The exhaled breath contains up
to 5.6 percent carbon dioxide. The greatest
physiological effect of carbon dioxide is to
stimulate the respiratory center, thereby controlling
the volume and rate of respiration. It is
able to cause dilation and constriction of blood
vessels and is a vital constituent of the acid-base
mechanism that controls the pH of the blood.
Carbon dioxide acts as a stimulant and a depressant
on the central nervous system. Increases
in heart rate and blood pressure have
been noted at a concentration of 7.6 percent,
and dyspnea (labored breathing), headache,
dizziness, and sweating occur if exposure at that
level is prolonged. At concentrations of 10 percent
and above, unconsciousness can result in I
minute or less. Impainnent in perfonnance has
been noted during prolonged exposure to concentrations
of 3 percent carbon dioxide even
when the oxygen concentration was 21 percent. | [Environmental Fate]
Carbon dioxide is an asphyxiant, means it causes toxicity by
displacing oxygen from the breathing atmosphere primarily in
enclosed spaces or in open spaces due to sudden release of
massive amounts of CO2 (for example, forests fire or natural
emission during a volcanic eruption) and results in hypoxia.
Thehumanbody produces about 12 000–13 000 mmols per day
of CO2 and is excreted primarily via lungs. The CO2 concentration
in plasma is maintained within a narrow range of
40±5 mm Hg (4.7–6 KPa). At plasma concentration of
22.5mmHg (3 KPa) or less death can occur within few minutes.
The cause of death in breathing high concentration ofCO2 is due
to CO2 poisoning, that results in rapid decrease in blood pH
(respiratory acidosis,
Low concentrations of CO2 in the air, or insufficient time for
CO2 in blood to exchange with oxygen (O2) in air such as in the
situations of hyperventilation, can lead to an increase in blood
pH (respiratory alkalosis, >pH 7.45). The reaction of CO2 with
water in the body is catalyzed by the enzyme carbonic anhydrases
(or carbonate dehydratases), which leads to formation of carbonic
acid, followed by dissociation into protons (H+) and bicarbonate
(HCO3-
). Carbonic acid is buffered in the cell primarily
by hemoglobin and proteins, which have limited capacity. | [storage]
Extremely stable and chemically nonreactive. Store in a tightly
sealed cylinder. Avoid exposure to excessive heat. | [Toxicity evaluation]
The CO2 cycle is part of carbon cycle in the ecosystem. Carbon
dioxide cycles in the environment (atmospheric air and surface
water) through respiration (aerobic and anaerobic), photosynthesis,
decomposition, and release from earth’s carbon sinks
(fossil fuels – coal, petroleum, methane; and calcium carbonate
rocks) during combustion. In water, dissolved CO2 reacts with
calcium to form calcium carbonate and precipitates to the ocean
floor. Few examples of most common reactions in the CO2 and carbon cycles in animals, plants, and the environment are presented
below. Most of these reactions either use or produce
energy. | [Regulatory Status]
