perchloroetylén

Perchloroethylene, commonly known as perc, is a colorless, non-flammable liquid with a sweet, chloroform-like odor. It is a chlorinated hydrocarbon that is widely used as a solvent in industrial and dry cleaning processes. Perchloroethylene is effective at dissolving fats, oils, and greases, making it useful for cleaning and degreasing applications. It is also used in the production of certain plastics and as a propellant in aerosol cans.

The chemical formula for perchloroethylene is C2Cl4. It is a versatile solvent due to its ability to dissolve a wide range of substances, including rubber, plastics, and some metals. However, its use has been a subject of concern due to its potential health and environmental impacts. Perchloroethylene can be absorbed through the skin, inhaled, or ingested, and exposure can lead to health issues such as liver damage, kidney problems, and neurological effects. It is also a potent greenhouse gas and can contribute to ozone depletion.

Regulations regarding the use and disposal of perchloroethylene vary by country, but many areas have implemented restrictions to minimize its environmental impact. The substance is classified as a probable human carcinogen by the International Agency for Research on Cancer. As a result, efforts are being made to find safer alternatives and to manage its use and disposal more responsibly.
