Ethylene Dichloride To Vinyl Chloride

Vinyl chloride is produced from ethylene in two step process.

Ethylene dichloride to vinyl chloride.

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. Direct chlorination routes require a high. It is a colorless liquid with a chloroform like odor. 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 first reacts with chlorine to produce ethylene dichloride. 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. An owner or operator of an ethylene dichloride vinyl chloride and or polyvinyl chloride plant shall comply with the requirements of this section. 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. 1 2 dichloroethane ethylene chloride glycol dichloride colorless liquid with a pleasant chloroform like odor. 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. 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.

It is also used as an intermediate for other organic chemical. 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. Vinyl chloride monomer vcm chloroethene the major precursor for pvc production. 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.

Flow sheet of production of ethylene dichloride. 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. Ethylene dichloride is also used generally as an intermediate for other organic chemical compounds and as a solvent. Edc is used primarily in the production of vinyl chloride monomer vcm.

Decomposes slowly becomes acidic darkens in color.
