tetrahloroetüleeni

Tetrachloroethene, also known as perchloroethylene or PCE, is a chlorinated hydrocarbon with the chemical formula C2Cl4. It is a colorless liquid at room temperature with a sweet odor. Tetrachloroethene is a nonflammable compound and is widely used as a solvent due to its ability to dissolve oils, greases, and other organic substances.

Its primary application is in the dry cleaning industry, where it is used to clean clothes without water. It is also employed as a degreasing agent for metals and in the production of refrigerants and other chemicals. Historically, it has been used in applications such as paint stripping and as an aerosol propellant.

Tetrachloroethene is volatile and can evaporate into the air. It is persistent in the environment, particularly in groundwater. Exposure can occur through inhalation or skin contact. In occupational settings, ventilation and personal protective equipment are important to minimize exposure. Health effects associated with significant exposure can include dizziness, headaches, and liver or kidney damage. It is classified as a possible human carcinogen by some regulatory agencies. Due to environmental and health concerns, its use and disposal are regulated in many regions.
