Vinyl Chloride Reactions

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.

Vinyl chloride reactions.

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. Ethylene dichloride vinyl chloride monomer hydrogen chloride. Vinyl chloride is primarily used to make polyvinyl chloride to manufacture plastics. Heating 1 2 dichloroethane in the presence of a charcoal catalyst gives vinyl chloride.

The reaction tolerates various functional groups and can be conducted under open air. 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. In one ethylene is converted to 1 2 dichloroethane ethylene chloride by reaction with chlorine. Polyvinyl chloride is a white rigid quite brittle solid.

The major industrial preparation of vinyl chloride begins with ethylene and has two variants. About 13 billion kilograms are produced annually. Pvc is made by subjecting vinyl chloride to highly reactive compounds known as free radical initiators. Vinyl chloride is produced from ethylene in two step process.

This produces further ethylene dichloride. This polymerisation reaction proceeds by a free radical mechanism.
