Vinyl Chloride Reactions

The hydrogen chloride is reacted with more ethylene in the presence of oxygen a reaction known as oxychlorination.

Vinyl chloride reactions.

Vinyl chloride is primarily used to make polyvinyl chloride to manufacture plastics. Under the action of the initiators the. Pvc is made by subjecting vinyl chloride to highly reactive compounds known as free radical initiators. Vinyl chloride ch 2 chcl also known as chloroethylene is most often obtained by reacting ethylene with oxygen and hydrogen chloride over a copper catalyst it is a toxic and carcinogenic gas that is handled under special protective procedures.

Polyvinyl chloride is produced in an addition polymerisation reaction using the chloroethene vinyl chloride monomer. Vinyl chloride is a chlorinated hydrocarbon occurring as a colorless highly flammable gas with a mild sweet odor that may emit toxic fumes of carbon dioxide carbon monoxide hydrogen chloride and phosgene when heated to decomposition. Polyvinyl chloride is a white rigid quite brittle solid. Heating 1 2 dichloroethane in the presence of a charcoal catalyst gives vinyl chloride.

In one ethylene is converted to 1 2 dichloroethane ethylene chloride by reaction with chlorine. Ethylene dichloride vinyl chloride monomer hydrogen chloride. This polymerisation reaction proceeds by a free radical mechanism. The reaction tolerates various functional groups and can be conducted under open air.

The major industrial preparation of vinyl chloride begins with ethylene and has two variants. Vinyl chloride is an organochloride with the formula h 2 c chcl that is also called vinyl chloride monomer vcm or chloroethene this colorless compound is an important industrial chemical chiefly used to produce the polymer polyvinyl chloride pvc. This produces further ethylene dichloride. Vinyl chloride is produced from ethylene in two step process.

About 13 billion kilograms are produced annually. Additives are used to modify the properties of polyvinyl chloride to make it more useful.
