Is trichloroethylene the same as trichloroethane?
The chemical compound trichloroethylene is a halocarbon commonly used as an industrial solvent. It is a clear, colourless non-flammable liquid with a chloroform-like sweet smell. It should not be confused with the similar 1,1,1-trichloroethane, which is commonly known as chlorothene. The IUPAC name is trichloroethene.
Is trichloroethane an organic solvent?

Where is trichloroethane found?
TCE may be found in the air, water, and soil at places where it is produced or used. It breaks down slowly and remains in the environment for a long time. It readily passes through soil and can accumulate in groundwater.
How many constitutional isomers are possible for trichloroethane?
trichloroethane, either of two isomeric colourless, nonflammable liquids belonging to the family of halogenated hydrocarbons.
Is trichloroethane saturated?
Measurements of methyl chloroform or 1,1,1-trichloroethane (CH3CCl3) showed that this compound was significantly unsaturated in the equatorial Pacific Ocean (Butler et al., 1991).
When was trichloroethylene banned?
The United States Food and Drug Administration (FDA, 1977) banned these uses of trichloroethylene because of its toxicity; its use in cosmetic and drug products was also discontinued (Mertens, 1993).
Is trichloroethane a VOC?
TCE is a clear, colorless liquid with a sweet, fruity odor. We’ve made it green in the illustrations. TCE is considered a volatile organic compound, or VOC, because it evaporates easily into the air.
Why was trichloroethylene banned?
In December 2016, using its authority under the newly strengthened Toxic Substances Control Act (TSCA), EPA proposed to ban the use of trichloroethylene (TCE) in aerosol degreasing and spot cleaning in dry cleaning facilities, after finding excessive risks to workers, consumers, and bystanders.
Is trichloroethane a TCE?
Trichloroethene (also known as trichloroethylene or TCE) is a human-made chemical. It is volatile, meaning it readily evaporates at room temperature into the air, where you can sometimes smell it.
Is trichloroethylene a carcinogen?
The Department of Health and Human Services (DHHS) considers trichloroethylene to be a known human carcinogen. The International Agency for Research on Cancer (IARC) classified trichloroethylene as carcinogenic to humans. The EPA has characterized trichloroethylene as carcinogenic to humans by all routes of exposure.
Is TCE a listed hazardous waste?
[40 CFR 261.33(f)] Unused trichloroethylene is listed as a U228.
