Ethylene dichloride

Ethylene dichloride (EDC), also known as 1,2-dichloroethane, is a colorless liquid with a chloroform-like odor. It is a widely used and important chemical commodity, primarily used as a raw material for the production of vinyl chloride, which is used to make a variety of plastic and vinyl products.

History

Ethylene dichloride has been produced since the 1800s. The process of its production has evolved over time, with the most significant development being the introduction of the direct chlorination method in the 1960s.

Production

Ethylene dichloride is produced through one of two methods: direct chlorination or oxychlorination. In direct chlorination, ethylene and chlorine are combined to produce ethylene dichloride. In oxychlorination, ethylene reacts with hydrogen chloride and oxygen to produce ethylene dichloride.

Uses

The primary use of ethylene dichloride is in the production of vinyl chloride, which is used to make polyvinyl chloride (PVC). PVC is used in a wide range of products, including pipes, cable coatings, and packaging materials. Ethylene dichloride is also used as a solvent and in the manufacture of other chemicals.

Health and Environmental Effects

Exposure to ethylene dichloride can have serious health effects, including damage to the liver, kidney, and heart. It is also a suspected carcinogen. The release of ethylene dichloride into the environment can have harmful effects on wildlife and ecosystems.

Regulation

Due to its potential health and environmental effects, the production and use of ethylene dichloride is regulated in many countries. Regulations may include limits on emissions, requirements for handling and disposal, and restrictions on its use in certain products.
