Carbon tetrachloride, also known by many other names (such as carbon tet for short and tetrachloromethane, also recognised by the IUPAC), is a chemical compound with the chemical formula CCl 4. It is a non-flammable, dense, colourless liquid with a "sweet" chloroform-like odour that can be detected at low levels.
Chloroform undergoes further chlorination to yield carbon tetrachloride (CCl 4): CHCl 3 + Cl 2 → CCl 4 + HCl The output of this process is a mixture of the four chloromethanes: chloromethane , methylene chloride (dichloromethane), trichloromethane (chloroform), and tetrachloromethane (carbon tetrachloride).

Organochlorine chemistry is concerned with the properties of organochlorine compounds, or organochlorides, organic compounds that contain one or more carbon–chlorine bonds. [1] The chloroalkane class (alkanes with one or more hydrogens substituted by chlorine) includes common examples. The wide structural variety and divergent chemical ...
Tetrachloride may refer to: . Carbon tetrachloride, CCl 4, also known as carbon tet; Chromium tetrachloride, CrCl 4; Germanium tetrachloride, GeCl 4, a colourless liquid used as an intermediate in the production of purified germanium metal
Carbon tetrachloride (CCl 4) can turn into phosgene when exposed to heat in air. This was a problem as carbon tetrachloride is an effective fire suppressant and was formerly in widespread use in fire extinguishers. [15] There are reports of fatalities caused by its use to fight fires in confined spaces. [16]
Carbon tetrachloride (CCl 4) was once widely used in dry cleaning as the first chlorinated solvent, but its use was abandoned after its high hepatotoxicity was discovered. 1,1,1-Trichloroethane was also used in dry cleaning, until its use was banned due to its harmful effects on the ozone layer.
It can also be produced by the reaction of lithium metal and carbon tetrachloride at 900 °C: [2] [3] 8 Li + CCl 4 → CLi 4 + 4 LiCl. However, this method also produces byproducts, such as lithium carbide.
