Molecular formula C2Cl4

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.


It is mainly used as organic solvent, dry cleaner and metal degreaser. It can be applied to all kinds of nature and synthetic fabrics as a dry cleaner and the fabric will be soft, glossy. It can also be used as the raw material for HCFC-123, HCFC-124, HCFC-125, HCFC-134a etc.

Other areas of application:

• degreasing metals in mechanical engineering, instrument,

• for machining printed circuit boards,

• in the production of medical needles

• in the wood industry,

• in the production of reactive dyes.
