12Dihaloethane

1,2-Dihaloethane refers to a class of organic compounds with the general formula XCH2CH2X, where X represents a halogen atom such as chlorine, bromine, or iodine. The most common examples are 1,2-dichloroethane and 1,2-dibromoethane. These compounds are typically colorless liquids with a sweet odor.

1,2-Dichloroethane, also known as ethylene dichloride (EDC), is a significant industrial chemical. It is primarily produced by the direct chlorination or oxychlorination of ethylene. Its main application is as a precursor in the manufacture of vinyl chloride monomer (VCM), which is then polymerized to form polyvinyl chloride (PVC). EDC is also used as a solvent, although its use in this capacity has declined due to health and environmental concerns.

1,2-Dibromoethane, or ethylene dibromide (EDB), has historically been used as a fumigant for agricultural products and as an additive in leaded gasoline to scavenge lead deposits. However, due to its toxicity and carcinogenic potential, its use has been severely restricted or banned in many countries.

1,2-Dihaloethanes are generally considered toxic and potentially carcinogenic. Exposure can occur through inhalation, skin contact, or ingestion. They are volatile and can contaminate air, water, and soil. Proper handling and disposal procedures are essential when working with these compounds. Environmental regulations often govern their production, use, and release.
