Carbon tetrachloride
A compound consisting of one carbon atom and four chlorine atoms. It is an ozone depleting substance. Carbon tetrachloride was widely used as a raw material in many industrial applications, including the production of chlorofluorocarbons, and as a solvent. Solvent use was ended in the United States when it was discovered to be carcinogenic. See ozone depleting substance. (source: EPA) Background from Wikipedia Carbon tetrachloride, also known by other names (see Table) is the chemical compound CCl4. It is widely used in synthetic chemistry and formerly widely used in fire extinguishers and refrigeration, but largely abandoned. At room temperature and pressure, it is a colorless liquid with a "sweet" smell that can be detected at low levels. Both carbon tetrachloride and tetrachloromethane are acceptable names under IUPAC nomenclature, depending on whether it is seen as an inorganic or an organic compound. Colloquially, it is called "carbon tet". Trade names include Benzinoform, Freon 10, Halon 104, Tetraform, and Tetrasol.
