Why is too much carbon dioxide a bad thing?
If your blood becomes saturated with too much CO2, you develop the condition known as hypercapnia. Increased levels of CO2 also affect the pH level of your blood, turning it more acidic.

What is carbon dioxide used for?
Carbon dioxide gas is used to make urea (used as a fertilizer and in automobile systems and medicine), methanol, inorganic and organic carbonates, polyurethanes and sodium salicylate. Carbon dioxide is combined with epoxides to create plastics and polymers.
What is the purpose of carbon dioxide in fire extinguishers?
Carbon dioxide-based fire extinguishers effectively manage electrical fires and those caused by solvents, fuels and oils.
What are the uses of CO2?
On this page, we describe some of the industrial uses of carbon dioxide.
Enhanced Oil and Gas Recovery
Another important CO₂ use is a process known as EOR/EGR, which is when CO₂ is used to help extract shale oil and gas from wells by injecting the carbon dioxide under the ground. It is an important industrial application, as many million tons of CO₂ are pumped into such wells each year.
Ask us anything
These are not all the possible applications of CO₂, so we will update this page with more information as time goes by.
What are carbonates used for?
Carbonates are useful and often greener substitutes for toxic phosgene (COCl 2) and dimethyl sulfate in a host of chemical reactions, Li said. They also serve well as solvents, especially in medicines and cosmetics, and they are electrolytes of choice in lithium-ion batteries.
What is foam used for?
The foams are used for insulation and seat cushions, among other applications. "About 150 million tons of plastics is produced globally in a year, and most of it is nonbiodegradable and from energy-intensive processes that use petroleum-based feedstocks," Coates told C&EN.
What is the Dubois catalyst?
Like that of other groups, DuBois' idea is to develop a catalyst capable of reducing CO 2 to useful fuels. In the case of methanol, the six electrons for the conversion could be supplied by a solar photovoltaic device and the six hydrogen ions could come from water, he said.
Is carbon monoxide a gas?
Carbon monoxide can be used in a host of organic syntheses, but it's best known as a component of synthesis gas (a mixture of CO and H 2 ), which is an important feedstock in the chemical industry for making hydrocarbons via Fischer-Tropsch reactions. Lots of opportunities exist, Rayner believes.
Is carbon dioxide flammable?
CARBON DIOXIDE is nontoxic, nonflammable, and essentially free for the taking. Those attributes make it sound like CO2 could be a great feedstock for making commodity chemicals, fuels, and materials—and it already is playing that role for a few applications. But there are a few catches.
Is carbon dioxide a solvent?
Carbon dioxide also could be used more widely as a solvent, he added. For example, supercritical CO 2 (the state existing at 31.0 °C and 72.8 atm) offers advantages in terms of stereochemical control, product purification, and environmental issues for synthesizing fine chemicals and pharmaceuticals, Rayner noted.
How does CO2 help the environment?
CO2 utilisation can help in two main ways: the removal and long-term storage of atmospheric CO2; and the reduction of CO2 emissions to the atmosphere. Potentially, using CO2 to make valuable products might also offset some of the costs of climate change mitigation.
What is CO2 utilisation?
Conventionally, “ CO2 utilisation ” is an industrial process that makes an economically valuable product using CO2 at concentrations above atmospheric levels. CO2 is either transformed using chemical reactions into materials, chemicals and fuels, or it is used directly in processes such as enhanced oil recovery.
Is CO2 utilisation beneficial?
Furthermore, even if CO2 utilisation were successful, that does not necessarily mean it would be beneficial for the climate. If done without due consideration, CO2 utilisation – in common with other approaches that remove and/or store CO2 – might not contribute to mitigation at all.
Is CO2 utilisation a big business?
Overall, CO2 utilisation has the potential to operate at large scale and at low cost, meaning it could be big business in the future.
What is carbon dioxide used for?
The compound has varied commercial uses but one of its greatest uses as a chemical is in the production of carbonated beverages; it provides the sparkle in carbonated beverages such as soda water, beer and sparkling wine.
How is carbon dioxide used in oil recovery?
Carbon dioxide is used in enhanced oil recovery where it is injected into or adjacent to producing oil wells, usually under supercritical conditions, when it becomes miscible with the oil. This approach can increase original oil recovery by reducing residual oil saturation by between 7% to 23% additional to primary extraction. It acts as both a pressurizing agent and, when dissolved into the underground crude oil, significantly reduces its viscosity, and changing surface chemistry enabling the oil to flow more rapidly through the reservoir to the removal well. In mature oil fields, extensive pipe networks are used to carry the carbon dioxide to the injection points.
How much carbon dioxide does the human body produce?
The body produces approximately 2.3 pounds (1.0 kg) of carbon dioxide per day per person , containing 0.63 pounds (290 g) of carbon. In humans, this carbon dioxide is carried through the venous system and is breathed out through the lungs, resulting in lower concentrations in the arteries.
What gases are used for welding?
It is one of the most commonly used compressed gases for pneumatic (pressurized gas) systems in portable pressure tools. Carbon dioxide is also used as an atmosphere for welding, although in the welding arc, it reacts to oxidize most metals. Use in the automotive industry is common despite significant evidence that welds made in carbon dioxide are more brittle than those made in more inert atmospheres. When used for MIG welding, CO 2 use is sometimes referred to as MAG welding, for Metal Active Gas, as CO 2 can react at these high temperatures. It tends to produce a hotter puddle than truly inert atmospheres, improving the flow characteristics. Although, this may be due to atmospheric reactions occurring at the puddle site. This is usually the opposite of the desired effect when welding, as it tends to embrittle the site, but may not be a problem for general mild steel welding, where ultimate ductility is not a major concern.
How much carbon dioxide is toxic to animals?
At very high concentrations (100 times atmospheric concentration, or greater), carbon dioxide can be toxic to animal life, so raising the concentration to 10,000 ppm (1%) or higher for several hours will eliminate pests such as whiteflies and spider mites in a greenhouse.
What is the length of a carbon-oxygen bond?
The carbon–oxygen bond length is 116.3 pm, noticeably shorter than the bond length of a C–O single bond and even shorter than most other C–O multiply-bonded functional groups. Since it is centrosymmetric, the molecule has no electrical dipole . Stretching and bending oscillations of the CO 2 carbon dioxide molecule.
How is carbon dioxide returned to water?
It is returned to water via the gills of fish and to the air via the lungs of air-breathing land animals, including humans. Carbon dioxide is produced during the processes of decay of organic materials and the fermentation of sugars in bread, beer and wine making.
