VINYL CHLORIDE PRODUCTION - University of Oklahoma

production of vinyl chloride by this method" (21). However, as ethylene became more plentiful in the early 50's, commercial processes were developed to produce vinyl chloride from chlorine and ethylene via EDC, namely, the balanced ethylene route. Today the balanced ethylene is responsible for well over 90% of the world's vinyl

Vinyl Chloride 2000 – Chemical production and .

In the ethylene-based route, vinyl chloride is manufactured by the pyrolysis of ethylene di-chloride. Ethylene dichloride is in turn produced by direct chlorination or oxychlorination of ethylene. For direct chlorination, we evaluate and compare liquid-phase high-temperature and low-temperature chlorination processes as well as a gas-phase process.
