DETAIL
The chemical compound 1,2-dichloroethane, commonly known as 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.

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.

The hydrogen chloride can be re-used in the production of more 1,2-dichloroethane via the oxychlorination route described above. 

Other uses
1,2-Dichloroethane has been used as degreaser and paint remover but is now banned from use due to its toxicity and possible carcinogenity. As a useful 'building block' reagent, it is used as an intermediate in the production of diverse organic compounds such as ethylenediamine. In the laboratory it is occasionally used as a source of chlorine, with elimination of ethene and chloride.

Via several steps, 1,2-dichloroethane is a precursor to 1,1,1-trichloroethane, which is used in dry cleaning. Historically, 1,2-dichloroethane was used as an anti-knock additive in leaded fuels to scavenge lead from cylinders and valves preventing buildup .
