The chemical compound 1,2-dichloroethane (DCE) commonly known by its old name of ethylene dichloride (EDC), is a chlorinated hydrocarbon. The most common use of 1,2-dichloroethane is in the production of vinyl chloride which is used to make a variety of plastic and vinyl products including polyvinyl chloride (PVC) pipes, furniture and automobile upholstery, wall coverings, housewares, and automobile parts. It is a colourless liquid with a chloroform-like odour. 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.〔Manfred Rossberg, Wilhelm Lendle, Gerhard Pfleiderer, Adolf Tögel, Eberhard-Ludwig Dreher, Ernst Langer, Heinz Rassaerts, Peter Kleinschmidt, Heinz Strack, Richard Cook, Uwe Beck, Karl-August Lipper, Theodore R.

==History==
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'' ((オランダ語:Society of Dutch Chemists)), were the first to produce 1,2-dichloroethane from olefiant gas (oil-making gas, ethylene) and chlorine gas.〔Deimann, van Troostwyk, Bondt and Louwrenburgh (1795) ("Ueber die Gasarten, welche man aus Verbindungen von starker Vitriolsäure und Alkohol erhält" ) (On the types of gases which one obtains from combinations of strong vitriolic acid and alcohol), ''Chemische Annalen'' … , 2 : 195-205, 310-316, 430-440. The production and characterization of 1,2-dichloroethane appear on pages 200-202. The investigators were trying to detect the presence of carbon (''Kohl'') in ethylene (''Luft'', literally, "air") by adding chlorine (''zündend Salzgas'', literally, "burning gas from salt"). Instead of the expected soot, an oil (''Oehl'') formed.〕 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.
