Ethylene Dichloride, also known as 1,2-dichloroethane, is a colorless, sweet-smelling liquid used primarily as a solvent and in the production of vinyl chloride, which is essential for making PVC (polyvinyl chloride) plastic. It is produced through the chlorination of ethylene, a common petrochemical. This chemical is classified as a hazardous substance due to its potential health effects, including respiratory issues and liver damage upon prolonged exposure. Proper safety measures are essential when handling ethylene dichloride to minimize risks to human health and the environment.
