Ethylene dichloride (EDC), systematically known as 1,2-dichloroethane is, together with vinyl chloride monomer (VCM) or chloroethene, the major precursor for PVC production.

From 1795 on, ethylene was referred to as the olefiant gas (oil-making gas), because it combined with chlorine to produce the oil of the Dutch chemists (ethylenedichloride), first synthesized in 1795 by a collaboration of four Dutch chemists.
Ethylene can be chlorinated to produce ethylenedichloride (1,2-Dichloroethane), a precursor to the plastic polyvinyl chloride, or combined with benzene to produce ethylbenzene, which is used in the manufacture of polystyrene, another important plastic.
Ethylene and gibberellin (or brassinosteroid) may be released when the plant must either cut back in size, or survive on stored resources, for exmaple during the night.
Wheat treated with a mixture of carbon tetrachloride, ethylenedichloride, and ethylene dibromide (60:35:5 per cent by volume) at the normal dosage had 76 ppm of organic chloride in the wheat and 17, 22, and 58 ppm of ethylenedichloride in the flour, shorts, and bran, respectively (Munsey, 1957).
The origin of the cereals with ethylenedichloride residues and the amounts found were: United States 5 ppm Argentina 1.4 ppm 70 ppm 70 ppm FATE OF RESIDUES In storage and processing After wheat containing 140 ppm of ethylenedichloride was cleaned and tempered, the residue fell to 41 ppm.
Wheat with 34.6 ppm of ethylenedichloride had 17.8 ppm after cleaning and tempering, and residues in the fractions after milling were 3 ppm in the flour, 3.5 ppm in the shorts, 22.8 ppm in the bran, and 12.0 ppm in the germ (Conroy, Walkden, and Farrell, 1957).
