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 ...

1,2-Dichloroethylene or 1,2-DCE is the name for a pair of organochlorine compounds with the molecular formula C 2 H 2 Cl 2.The two compounds are isomers, each being colorless liquids with a sweet odor.
Today, most trichloroethylene is produced from ethylene. First, ethylene is chlorinated over a ferric chloride catalyst to produce 1,2-dichloroethane: CH 2 =CH 2 + Cl 2 → ClCH 2 CH 2 Cl. When heated to around 400 °C with additional chlorine, 1,2-dichloroethane is converted to trichloroethylene: ClCH 2 CH 2 Cl + 2 Cl 2 → ClCH=CCl 2 + 3 HCl
1,2-Dichloroethane, ClCH 2 CH 2 Cl (also known as ethylene dichloride, EDC), can be prepared by halogenation of ethane or ethylene, inexpensive starting materials. EDC thermally converts into vinyl chloride and anhydrous HCl. This production method has become the major route to vinyl chloride since the late 1950s. [2]
Ethylene chloride is a chemical name that can refer to either of the following compounds: 1,2-dichloroethane: formula C 2 H 4 Cl 2: vinyl chloride: formula C 2 H 3 Cl
In January 2022, an ethylene dichloride tank exploded at a Westlake facility in Westlake, Louisiana injuring 6 workers and triggering a shelter-in-place order. [13] Westlake facilities in Louisiana have had uncontrolled chemical releases including benzene, chloroform, ethylene dichloride, hydrogen chloride and vinyl chloride. [14]
Non condensible gases and remaining chlorine gas are vented off as part of the pressure control of the liquefaction systems. These gases are routed to a gas scrubber, producing sodium hypochlorite, or used in the production of hydrochloric acid (by combustion with hydrogen) or ethylene dichloride (by reaction with ethylene).
