Ethyne to vinyl chloride
WebThe vinyls chain— ethylene dichloride (EDC), vinyl chloride monomer (VCM), and polyvinyl chloride (PVC)—is a key component of the global petrochemical and thermoplastics sectors. VCM production is based mainly on the ethylene feedstock route, except in mainland China, where the acetylene-based capacity dominates. WebVinyl chloride monomer (VCM) is the key chemical precursor to PVC. It is produced commercially by combining a hydrocarbon feedstock, namely ethylene, obtained by …

Webethylene, acetylene, and chlorine give two moles of vinyl chloride with a minimum of by-products. Hard cracking of hydrocarbons to a 1:1 molar mixture of ethylene and acetylene for use as feedstock for vinyl chloride production is done. The crude stream from the tubular reactor contains the main product, as well as unreacted amount of WebVinyl chloride was first produced commercially in the 1930s by reacting hydrogen chloride with acetylene. Currently, vinyl chloride is produced commercially by the chlorination of ethylene through one of two processes, direct chlorination or oxychlorination. Direct chlorination reacts ethylene with chlorine to produce 1,2-dichloroethane.
