tetrahloroetüleen

tetrahloroetüleen, also known as tetrachloroethylene or perchloroethylene, is a chlorinated hydrocarbon with the chemical formula C2Cl4. It is a colorless liquid with a distinct sweet odor. This chemical is primarily used as a dry cleaning solvent and also finds applications in metal degreasing processes. Its ability to dissolve oils and greases makes it effective for these industrial uses.

Industrially, tetrahloroetüleen is produced through the chlorination of ethylene or other hydrocarbons. It has been widely used in the dry cleaning industry for decades due to its effectiveness and relatively low flammability compared to other solvents. However, concerns regarding its environmental persistence and potential health effects have led to increased regulation and a move towards alternative solvents in some regions.

Exposure to tetrahloroetüleen can occur through inhalation of vapors or skin contact. While it is an effective solvent, it is also classified as a possible human carcinogen. Occupational exposure limits are in place to protect workers in industries where it is used. Environmental concerns include its potential to contaminate groundwater and its persistence in the environment. Efforts are ongoing to develop and implement safer and more sustainable alternatives for its industrial applications.
