Description
Tetrachloroethylene is a clear, colorless, volatile, nonflammable liquid with an ethereal odor. Insoluble in water. Vapors heavier than air. Density approximately 13.5 lb/gal. Used as dry cleaning solvent, a degreasing solvent, a drying agent for metals, and in the manufacture of other chemicals. Tetrachloroethylene is a clear, colorless, nonflammable liquid with a characteristic odor. The odor is noticeable @ 47 ppm, though after a short period it may become inconspicuous, thereby becoming an
Tetrachloroethylene, also known under the systematic name tetrachloroethene, or perchloroethylene (“perc” or “PERC”), and many other names, is a chlorocarbon with the formula Cl2C=CCl2. It is a colorless liquid widely used for dry cleaning of fabrics, hence it is sometimes called “dry-cleaning fluid.” It has a sweet odor detectable by most people at a concentration of 1 part per million (1 ppm). Worldwide production was about one million metric tons in 1985.

Uses
Tetrachloroethylene (PCE) is also known as perchloroethylene, tetrachloroethene, and 1,1,2,2- tetrachloroethene and is also commonly abbreviated to PER or PERC. Tetrachloroethylene is a volatile, chlorinated organic hydrocarbon that is widely used as a solvent in the dry-cleaning and textile-processing industries and as an agent for degreasing metal parts. It is an environmental contaminant that has been detected in the air, groundwater, surface waters, and soil (NRC, 2010). Tetrachloroethylene
