tetrachloroethylene
Sign in to saveAlso known as perchlorethylene, perchloroethylene, tetrachlorethylene, ethylene tetrachloride, 1,1,2,2-tetrachloroethylene, 1,1,2,2-tetrachloroethene, dicarbon tetrachloride, carbon bichloride
Tetrachloroethylene, also known as perchloroethylene or under the systematic name tetrachloroethene, and abbreviations such as perc, and PCE, is a chlorocarbon with the formula . 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, also known as perchloroethylene or under the systematic name tetrachloroethene, and abbreviations such as perc, and PCE, is a chlorocarbon with the formula . 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.
Because of its wide usage, tetrachloroethylene has been extensively assessed as a potential hazard, resulting in government publications about its potential for neurotoxicity and carcinogenesis from chronic or repeated exposure. Improper disposal has caused groundwater pollution.
