dichloroethylenes

Dichloroethylenes are a group of organic compounds that contain two chlorine atoms and two ethylene groups. They are classified as vinyl chlorides and are used in various industrial applications. The most common dichloroethylene is 1,2-dichloroethylene, which is a colorless, volatile liquid with a sweet, ether-like odor. It is used as a solvent, a chemical intermediate, and a fumigant. 1,2-Dichloroethylene is also a byproduct of the production of vinyl chloride, which is used to make polyvinyl chloride (PVC) plastics.

Another important dichloroethylene is 1,1-dichloroethylene, which is a colorless gas with a sweet, mustard-like odor. It is used as a solvent, a chemical intermediate, and a fumigant. 1,1-Dichloroethylene is also a byproduct of the production of vinyl chloride.

Dichloroethylenes are toxic and can cause serious health problems if inhaled, ingested, or absorbed through the skin. They can cause damage to the liver, kidneys, and central nervous system. They are also carcinogenic and can increase the risk of cancer.

Dichloroethylenes are regulated by various environmental and health agencies, including the Environmental Protection Agency (EPA) in the United States and the European Chemicals Agency (ECHA) in the European Union. They are subject to strict regulations regarding their production, use, and disposal to minimize their potential environmental and health impacts.
