Tetrachloroethane
Tetrachloroethane () may refer to either of two isomeric chemical compounds: * 1,1,1,2-Tetrachloroethane (R-130a) * 1,1,2,2-Tetrachloroethane (R-130) See also * Tetrachloroethene * Trichloroethane * Tetrafluoroethane * Tetrabromoethane 1,1,2,2-Tetrabromoethane, or simply tetrabromoethane (TBE), is a halogenated hydrocarbon, chemical formula C2H2Br4. Although three bromine atoms may bind to one of the carbon atoms creating 1,1,1,2-tetrabromoethane this is not thermodynamically fav ...

1,1,2,2-Tetrachloroethane
1,1,2,2-tetrachloroethane (TeCA), also known by the brand names Bonoform, Cellon and Westron, is an organic compound. It is colorless liquid and has a sweet odor. It is used as an industrial solvent and as a separation agent. TeCA is toxic and it can be inhaled, consumed or absorbed through the skin. After exposure, nausea, dizziness or even liver damage may occur. History 1,1,2,2-Tetrachloroethane and 1,1,1,2-Tetrachloroethane were discovered by Auguste Laurent in 1836. 1,1,2,2-tetrachloroethane was used in large amounts to produce other chemicals like trichloroethylene, tetrachloroethylene, and 1,2-dichloroethylene. Because of its possible carcinogen effects on humans, the production of 1,1,2,2-tetrachloroethane has decreased significantly and is no longer widely used as an end-product. It is however still generated as a byproduct and as an intermediate product during manufacturing, where low levels of the chemical have been detected in the air. Uses 1,1,2,2-Tetrachloroethan ...

1,1,1,2-Tetrachloroethane
1,1,1,2-Tetrachloroethane is a chlorinated hydrocarbon. It is a colorless liquid with a sweet chloroform-like odor. It is used as a solvent and in the production of wood stains and varnishes. It is an isomer of 1,1,2,2-tetrachloroethane. Production 1,1,1,2-Tetrachloroethane can be obtained by a two-step addition reaction of acetylene with chlorine (via dichloroethene), but this mainly produces 1,1,2,2-tetrachloroethane. : : It can be obtained directly by chlorination of 1,1,2-trichloroethane: : Safety IARC has classified 1,1,1,2-tetrachloroethane as a possible carcinogen for humans in 2014.

Tetrachloroethylene
Tetrachloroethylene, also known as perchloroethylene or under the systematic name tetrachloroethene, and abbreviations such as perc (or PERC), and PCE, is a chlorocarbon with the formula . It is a non-flammable, stable, colorless and heavy liquid widely used for dry cleaning of fabrics and occasionally as a highly effective automotive brake cleaner. It has a mildly sweet, sharp odor, detectable by most people at a concentration of 50 ppm. Tetrachloroethylene is regarded as a toxic substance, a human health hazard, and an environmental hazard. In 2020, the United States Environmental Protection Agency stated that "tetrachloroethylene exposure may harm the nervous system, liver, kidneys, and reproductive system, and may be harmful to unborn children", and reported that numerous toxicology agencies regard it as a carcinogen. History and production French chemist Henri Victor Regnault first synthesized tetrachloroethylene in 1839 by thermal decomposition of hexachloroethane f ...

Isomer
In chemistry, isomers are molecules or polyatomic ions with identical molecular formula – that is, the same number of atoms of each element (chemistry), element – but distinct arrangements of atoms in space. ''Isomerism'' refers to the existence or possibility of isomers. Isomers do not necessarily share similar chemical property, chemical or physical property, physical properties. Two main forms of isomerism are structural isomerism, structural (or constitutional) isomerism, in which ''chemical bond, bonds'' between the atoms differ; and stereoisomerism (or spatial isomerism), in which the bonds are the same but the ''relative positions'' of the atoms differ. Isomeric relationships form a hierarchy. Two chemicals might be the same constitutional isomer, but upon deeper analysis be stereoisomers of each other. Two molecules that are the same stereoisomer as each other might be in different conformational forms or be different Isotopologue, isotopologues. The depth of analy ...
