What are the uses for carbon monoxide

Carbon monoxide - DIMAG gases

What is carbon monoxide (carbon monoxide)?

Carbon monoxide (carbon monoxide) is a chemical compound consisting of carbon and oxygen, and is therefore assigned to the group of carbon oxides.
It is a colorless, tasteless and odorless, very toxic and flammable gas.
The empirical formula is: CO. The molecular structure can best be described using molecular orbital theory. The length of the bond indicates that it is a partial triple bond. The molecule has a low dipole moment and is very stable and isoelectronic due to the very stable nitrogen molecule.

Acquisition of carbon monoxide (carbon monoxide)

Carbon monoxide is not an over the counter gas. Preservation is associated with high legal requirements and conditions.

How is carbon monoxide (carbon monoxide) formed?

The gas is generated when one or more carbon-containing substances are not completely oxidized. Combustion in the absence of oxygen, or at high temperatures, causes z. B. Above mentioned formation of carbon monoxide. Carbon monoxide is flammable and burns with oxygen to form carbon dioxide (carbonic acid / carbon dioxide).

Use of carbon monoxide (carbon monoxide)

Carbon monoxide finds z. B. Application for:

  • Binding of plastic fibers in a pure carbon matrix for the production of CFRP
  • Manufacture of sodium forminate using sodium hydroxide
  • Conversion of methanol to acetic acid
  • Carbonylation Reactions in Organic Synthesis
  • Manufacture of iron
  • Production of formic acid via methyl forminate

Carbon Monoxide (Carbon Monoxide) Hazards

Carbon monoxide is a highly dangerous respiratory poison; when it gets into the bloodstream, it binds to the red blood pigment hemoglobin 325 times more strongly than oxygen. This means that if there is about 0.1% carbon monoxide in the air, half of the hemoglobin in the blood will bind with carbon monoxide over time.
At a concentration of approx. 1.28% in the air, death occurs within 1-2 minutes due to insufficient oxygen transport (i.e. suffocation).
Carbon monoxide in high concentrations reacts very strongly exothermically with oxygen if an ignition source is present. The ignition temperature is 605 ° C. The use of a doorbell or a light switch can already cause a strong exothermic reaction (explosion) through the formation of sparks.

Rescuing an injured person from a CO-suspicious situation can only be done with heavy breathing protection.

Effects of different doses of carbon monoxide (carbon monoxide)

According to studies, there is no danger for healthy adults with continuous exposure of 8 hours a day and a concentration of up to 115ppm. These can be intensified in risk groups with cardiovascular diseases. At higher concentrations above 150-300ppm, nausea, dizziness and drowsiness will result.

Disposal of carbon monoxide (carbon monoxide)

Since carbon monoxide is very toxic and very flammable in connection with oxygen, special care must be taken when disposing of it by flaming it.
