Ethylene dichloride to vinyl chloride.

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. The purified ethylene dichloride undergoes selective cracking to form vinyl chloride. Flow sheet of production of ethylene dichloride. It is a colorless liquid with a chloroform like odor.

Edc is used primarily in the production of vinyl chloride monomer vcm. Ethylene dichloride is also used generally as an intermediate for other organic chemical compounds and as a solvent. Vinyl chloride is produced from ethylene in two step process. Ethylene dichloride edc is a colorless to yellowish liquid with a faint chloroform type odour.

Ethylene dichloride edc ethylene dichloride or 1 2 dichloroethane was once called dutch oil in honor of the dutch scientists who first synthesized this compound from ethylene and chlorine gases in the late 18th century.
