112Trichloroethene

1,1,2-Trichloroethene, also known as vinyl trichloride, is a chlorinated hydrocarbon with the chemical formula C2HCl3. It is a colorless, non-flammable liquid with a sweet odor. This compound is primarily used as a solvent and degreaser in various industrial applications.

Historically, 1,1,2-trichloroethene was widely employed for metal cleaning and in the dry cleaning industry due to its excellent ability to dissolve oils, greases, and waxes. However, concerns regarding its environmental persistence and potential health effects have led to a significant reduction in its use. It can be released into the environment through industrial emissions, spills, and the disposal of contaminated materials.

Exposure to 1,1,2-trichloroethene can occur through inhalation, skin contact, or ingestion. It is classified as a possible human carcinogen by some regulatory agencies. Short-term exposure can cause dizziness, headaches, and nausea, while long-term exposure may lead to liver and kidney damage, as well as neurological effects. Due to these health and environmental concerns, many countries have implemented regulations to limit its production, use, and release. Alternative, less hazardous solvents are now commonly used in its place.
