Definition |
Tetrachloroethylene is a synthetic chemical. It is a clear, colorless, nonflammable liquid with a sweet, fruity odor like that of chloroform. It is volatile and readily evaporates at room temperature. |
Uses |
As of 1995 the estimated end-use pattern for tetrachloroethylene was (Agency for Toxic Substances and Disease Registry 1997.)
- chemical intermediates - 55%,
- metal cleaning and vapor degreasing - 25%,
- dry cleaning and textile processing - 15%, and
- other unspecified uses - 5%.
Tetrachloroethylene has also been used as (U.S. EPA 2005)
- an intermediate in the synthesis of fluorocarbons,
- an insulating/cooling fluid in electric transformers,
- a component in typewriter correction fluids,
- a veterinary medication against worms, and
- a grain protectant and fumigant.
|
Synonyms |
Chemical synonyms for tetrachloroethylene include
- tetrachloroethene,
- perchloroethylene,
- 1,1,2,2-tetrachloroethylene, and
- ethylene tetrachloride.
Other commonly used names are
- PCE,
- Perc,
- perchlor, and
- Perclene.
|
Key Points |
- Tetrachloroethylene is a synthetic chemical that is widely used for dry cleaning of fabrics and for metal-degreasing operations.
- Tetrachloroethylene is also used as a starting material for making other chemicals and is used in some consumer products.
