The process chosen for vinyl chloride production is a combination of two processes direct chlorination and oxychlorination.
Vinyl chloride monomer production process.
Vcm is used primarily for the production of polyvinyl chloride pvc homopolymer and copolymer resins.
At room temperature vcm is a gas with a sweet ethereal odor but in industrial processes it is most often handled as a liquid melting point 13 c.
Pvc consumption is second to low density polyethylene.
Its chemical formula is c2h3cl.
In the direct chlorination as well as in the oxychlorination process ethylene dichloride edc is produced.
Vinyl chloride also known as vinyl chloride monomer vcm and chloroethene is an organochloride compound.
Vcm production results in a number of unwanted.
Vinyl chloride was first produced in 1835 but did not go into regular production until the early twentieth century.
