Trichloroethylene (TCE) is a halocarbon with the formula C 2 HCl 3, commonly used as an industrial metal degreasing solvent. It is a clear, colourless, non-flammable, volatile liquid with a chloroform -like pleasant mild smell [ 3 ] and sweet taste. [ 9 ]
1,1,1-Trichloroethane is an excellent solvent for many organic compounds and also one of the least toxic of the chlorinated hydrocarbons.It is generally considered non-polar, but owing to the good polarizability of the chlorine atoms, it is a superior solvent for organic compounds that do not dissolve well in hydrocarbons such as hexane.
Trichloroethylene is a major byproduct, which is separated by distillation. Worldwide production was about 1 million metric tons (980,000 long tons; 1,100,000 short tons) in 1985. [11] Although in very small amounts, tetrachloroethylene occurs naturally in volcanoes along with trichloroethylene. [12]
1,1,2-Trichloroethane, vinyl trichloride or 1,1,2-TCA, is an organochloride solvent with the molecular formula C 2 H 3 Cl 3 and the structural formula CH 2 Cl—CHCl 2.It is a colourless, sweet-smelling liquid that does not dissolve in water, but is soluble in most organic solvents.
Reductive dechlorination is rarely useful in chemical synthesis, but is a key step in the biodegradation of several organochlorine persistent pollutants. [ citation needed ] Applications
Halocarbon compounds are chemical compounds in which one or more carbon atoms are linked by covalent bonds with one or more halogen atoms (fluorine, chlorine, bromine or iodine – group 17) resulting in the formation of organofluorine compounds, organochlorine compounds, organobromine compounds, and organoiodine compounds.
2,2,2-Trichloroethanol is the chemical compound with formula Cl 3 C−CH 2 OH.Its molecule can be described as that of ethanol, with the three hydrogen atoms at position 2 (the methyl group) replaced by chlorine atoms.
