Ethylene dichloride is also used generally as an intermediate for other organic chemical compounds, and as a solvent. Ethylene dichloride is produced through the iron(III) chloride catalyzed reaction of ethene (ethylene) and chlorine. H 2 C=CH 2 + Cl 2 → Cl-CH 2-CH 2-Cl In subsequent reactions, notably to vinyl chloride

MOGAS valves are ideal for the hazardous conditions of VCM production. This 12-inch ASME 300 Class C-Series valve has successfully isolated a VCM furnace at a major German chemical plant for 15 years before it required spare parts. VCM is a colorless gas manufactured using a series of chemical reactions from ethylene dichloride (EDC).

Vinyl chloride may be synthesized by a two-step process. First, ethylene is chlorinated to form 1,2-dichlorothane. Then the 1,2-dichloroethane is dehydrochlorinated to produce vinyl chloride and hydrogen chloride. At this point, the hydrogen chloride may be siphoned off from the vinyl chloride to react with oxygen and more ethylene to form 1,2 ...
