CARBON MONOXIDE

DOI: 10.1615/AtoZ.c.carbon_monoxide

Carbon Monoxide (CO) is a colorless and odorless gas slightly heavier than air. It is highly toxic and at low to medium concentration in air, it forms a flammable and explosive mixture. It is classified as one of the major air pollutants. There are a number of processes for its production from carbon dioxide, oxygen, coke and steam. It is also produced by combustion of organic compounds in an oxygen deficient atmosphere. It is used in metallurgy and in the organic synthesis of methanol, acetic acid, aldehydes and a number of other compounds.

Listed below are some of its physical characteristics:

Molecular weight: 28.011Critical temperature: 133.16 K
Melting point: 68.16 KCritical pressure: 3.498 MPa
Normal boiling point: 81.66KCritical density: 301 kg/m3
