Vinyl Chloride Monomer Production

This colorless compound is an important industrial chemical chiefly used to produce the polymer polyvinyl chloride pvc.

Vinyl chloride monomer production.

The five main processes used in the production of vinyl chloride monomer vcm are. The largest use for vinyl chloride monomer is in the production of polyvinyl chloride pvc homopolymer and copolymer resins. These pvc resins are converted to products for a number of end use markets. Vinyl chloride has been used in the past as an anaesthetic and as an aerosol spray propellant but its principle use has been to produce the polymer polyvinyl chloride pvc or vinyl.

Vcm is used primarily for the production of polyvinyl chloride pvc homopolymer and copolymer resins. It can be found at. Emulsion polymerization accounts for about 12 and bulk polymerization accounts for 8. Vinyl chloride also known as vinyl chloride monomer vcm and chloroethene is an organochloride compound.

Global production capacity of vinyl chloride monomer 2018 2023 published by m. About 13 billion kilograms are produced annually. Garside nov 6 2019 the global production capacity of vinyl chloride monomer vcm is expected to increase from. Vinyl chloride is an organochloride with the formula h 2 c chcl that is also called vinyl chloride monomer vcm or chloroethene.

More than half of the total vcm consumption is for construction related applications with pipe being the largest single product. About 80 of production involves suspension polymerization. 1 direct chlorination of ethylene to form edc 2 oxychlorination of ethylene to form from recycled hcl and oxygen 3 purification of edc 4 thermal cracking of edc to form vcm and hcl and 5 the purification of vcm. 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.

These processes are shown in figure 1. Vinyl chloride monomer vcm is one of the world s most important and largest commodity chemicals. Vinyl chloride monomer vcm production vinyl chloride monomer vcm is the key material from which pvc is made.
