Tetrachloroethylene

Tetrachloroethylene, also known as perchloroethylene or under the systematic name tetrachloroethene, and abbreviations such as perc, and PCE, is a chlorocarbon with the formula Cl2C=CCl2. It is a volatile, non-flammable, stable, colorless and dense liquid widely used for dry cleaning of fabrics and as a metal degreasing solvent, formerly as an oral anthelmintic. It has a mild, sweet, sharp odor, detectable by most people at a concentration of 50 ppm. Tetrachloroethylene is produced industrially by the chlorination or oxychlorination of hydrocarbons Wikipedia
