Vinyl Chloride Monomer Production

Emulsion polymerization accounts for about 12 and bulk polymerization accounts for 8.

Vinyl chloride monomer production. These processes are shown in figure 1. The largest use for vinyl chloride monomer is in the production of polyvinyl chloride pvc homopolymer and copolymer resins. Vinyl chloride is an organochloride with the formula h 2 c chcl that is also called vinyl chloride monomer vcm or chloroethene. 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.

Vinyl chloride monomer vcm production vinyl chloride monomer vcm is the key material from which pvc is made. Vinyl chloride also known as vinyl chloride monomer vcm and chloroethene is an organochloride compound. Production polyvinyl chloride is produced by polymerization of the vinyl chloride monomer vcm as shown. About 80 of production involves suspension polymerization.

It can be found at. 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. This colorless compound is an important industrial chemical chiefly used to produce the polymer polyvinyl chloride pvc. Vinyl chloride monomer vcm production and manufacturing process commercial production of vcm started in the 1920s based on the catalytic hydrochlorination of acetylene but this route suffered from high energy costs and has become obsolete except for china.

More than half of the total vcm consumption is for construction related applications with pipe being the largest single product. Global production capacity of vinyl chloride monomer 2018 2023 published by m. The five main processes used in the production of vinyl chloride monomer vcm are. 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 monomer vcm is one of the world s most important and largest commodity chemicals. Vcm is used primarily for the production of polyvinyl chloride pvc homopolymer and copolymer resins.
