Ethylene Dichloride To Vinyl Chloride

Vinyl chloride is produced from ethylene in two step process.

Ethylene dichloride to vinyl chloride.

Decomposes slowly becomes acidic darkens in color. Flow sheet of production of ethylene dichloride. Ethylene dichloride is also used generally as an intermediate for other organic chemical compounds and as a solvent. It is a colorless liquid with a chloroform like odor.

According to the united states environmental protection agency epa vinyl chloride emissions from polyvinyl chloride pvc ethylene dichloride edc and vinyl chloride monomer vcm plants cause or contribute to air pollution that may reasonably be anticipated to result in an increase in mortality or an increase in serious irreversible or. Ethylene dichloride is produced through the iron iii. 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. It is also used as an intermediate for other organic chemical.

Nowadays it is mainly used to produce vinyl chloride monomer vcm the major raw material for pvc production. The purified ethylene dichloride undergoes selective cracking to form vinyl chloride. Qatar vinyl company s edc is produced by oxychlorination and direct chlorination of ethylene at our petrochemical complex located in mesaieed industrial city mic mesaieed. Ethylene chloride c 2 h 4 cl 2 also called ethylene dichloride or 1 2 dichloroethane a colourless toxic volatile liquid having an odour resembling that of chloroform.

Except for an emergency relief discharge and except as provided in 61 65 d there is to be no discharge to the atmosphere from any relief valve on any equipment in vinyl chloride service. Ethylene dichloride edc is a colorless to yellowish liquid with a faint chloroform type odour. A relief valve discharge rvd. 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 conversion of ethylene chloride to vinyl chloride is carried out at temperatures of about 500 c 930 f in the presence of a catalyst. 1 2 dichloroethane ethylene chloride glycol dichloride colorless liquid with a pleasant chloroform like odor. Vinyl chloride monomer vcm chloroethene the major precursor for pvc production. 2 3 vinyl chloride from ethylene ethylene can be converted to vinyl chloride in a single stage i e without isolating the intermediate ethylene dichloride by either chlorination or oxychlorination routes as is the case with the balanced ethylene route.

Ethylene first reacts with chlorine to produce ethylene dichloride.
