The Chlorination Of Vinyl Chloride

Vcm is among the top twenty largest petrochemicals in world production.

The chlorination of vinyl chloride. The five main processes used in the production of vinyl chloride monomer vcm are. A plausible addition elimination mechanism is proposed. This catalytic method enables a green route to aryl z vinyl chlorides. The major industrial preparation of vinyl chloride begins with ethylene and has two variants.

About 13 billion kilograms are produced annually. The microstructure of cpvc and β β d2 cpvc was characterized by a combination of 1h nmr 13c nmr spectroscopy and analytically determined chlorine content. This colorless compound is an important industrial chemical chiefly used to produce the polymer polyvinyl chloride. In one ethylene is converted to 1 2 dichloroethane ethylene chloride by reaction with chlorine.

The reaction of aromatic ketones with bis trichloromethyl carbonate afforded aryl z vinyl chlorides in the presence of scandium triflate dmf and benzoyl chloride as catalysts. Samples of chlorinated poly vinyl chloride cpvc and chlorinated β β dideuterated poly vinyl chloride β β d2 cpvc were prepared under identical reaction conditions. Heating 1 2 dichloroethane in the presence of a charcoal catalyst gives vinyl chloride.
