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] Its IUPAC name is trichloroethene. Trichloroethylene has been sold under a variety of trade names.
Organochlorides such as trichloroethylene, tetrachloroethylene, dichloromethane and chloroform are commonly used as solvents and are referred to as "chlorinated solvents". [ citation needed ] Physical and chemical properties
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]
1,1,1-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.
Since the 1970s there have been longstanding, unresolved controversies over potential health hazards of trichloroethylene (TCE) and other halocarbon solvents that had been widely used for industrial cleaning (Anderson v. Grace 1986) (Scott & Cogliano 2000) (U.S. National Academies of Science 2004) (United States 2004).
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. It is an isomer of 1,1,1-trichloroethane, and a byproduct of ...
Trichloroethylene (TCE) is more aggressive than PCE but is very rarely used today. With superior degreasing properties, it was often used for industrial workwear/overalls cleaning in the past. It is chemically related to tetrachloroethylene. TCE is classified as carcinogenic to humans by the United States Environmental Protection Agency. [12]
Others from this series were Perklone (Tetrachloroethylene), Triklone (Trichloroethylene), Methoklone (Dichloromethane) and Genklene (1,1,1-Trichloroethane). [15] [16] CFC-113 is one of the three most popular CFCs, along with CFC-11 and CFC-12. [17] CFC-113 in laboratory analytics has been replaced by other solvents. [18]
