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 (b.p. 70.5 °C) and other chlorocarbons.

In 1794, physician Jan Rudolph Deiman, merchant Adriaan Paets van Troostwijk, chemist Anthoni Lauwerenburg, and botanist Nicolaas Bondt, under the name of Gezelschap der Hollandsche Scheikundigen (Dutch: Society of Dutch Chemists), were the first to produce 1,2-dichloroethane from olefiant gas (oil-making gas, ethylene) and chlorine gas. Although the Gezelschap in practice did not do much in-depth scientific research, they and their publications were highly regarded. Part of that acknowledgement is that 1,2-dichloroethane was called "Dutch oil" in old chemistry.

Nearly 20 million tons of 1,2-dichloroethane are produced in the United States, Western Europe, and Japan. Production is primarily achieved through the iron(III) chloride-catalysed reaction of ethene (ethylene) and chlorine.

1,2-dichloroethane is also generated by the copper(II) chloride-catalysed oxychlorination of ethylene:
