ETHYLENE DICHLORIDE
Ethylene dichloride (EDC), is a chlorinated hydrocarbon. It is a colourless liquid with a chloroform-like odour. The most common use of 1,2-dichloroethane is in the production of vinyl chloride, which is used to make polyvinyl chloride (PVC) pipes, furniture and automobile upholstery, wall coverings, housewares, and automobile parts. 1,2-Dichloroethane is also used generally as an intermediate for other organic chemical compounds, and as a solvent. It forms azeotropes with many other solvents, including water (at a boiling point of 70.5 °C or 158.9 °F or 343.6 K) and other chlorocarbons.

Dosage
Vinyl chloride monomer (VCM) production:
Approximately 95% of the world's production of 1,2-dichloroethane is used in the production of vinyl chloride monomer (VCM, chloroethene) with hydrogen chloride as a byproduct. VCM is the precursor to polyvinyl chloride.
- Cl−CH2−CH2−Cl → H2C=CH−Cl + HCl
The hydrogen chloride can be re-used in the production of more 1,2-dichloroethane via the oxychlorination route described above.
EDC is used primarily as a raw material in the manufacture of vinyl chloride monomer (VCM). The vinyl chloride, in turn is used to manufacture polyvinyl chloride (PVC) resin. EDC is also used as an intermediate in the manufacture of chlorinated and fluorinated compounds.
