Vinyl Chloride Monomer Production

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 production.

This is due mainly to the inherent strength of the c cl bond. Edc is then. Direct chlorination sees ethylene and chlorine react within a catalyst containing reactor to form edc. Caustic chlorine ethylene ethylene dichloride edc vinyl chloride monomer vcm suspension pvc resins specialty dispersion pvc resins.

It forms a liquid readily under increased pressure or at reduced temperatures. About 13 billion kilograms are produced annually. The global production capacity of vinyl chloride monomer vcm is expected to increase from approximately 49 million metric tons in 2018 to around 52 9 million metric tons five years later. Vcm is used primarily in the production of polyvinyl chloride pvc homopolymer and copolymer resins.

Vinyl chloride monomer vcm is one of the world s most important and largest commodity chemicals. Pvc has the advantage of being utilized in conversion and fabrication processes with great flexibility such that end products cover a wide. Vinyl chloride is an organochloride with the formula h 2 c chcl that is also called vinyl chloride monomer vcm or chloroethene this colorless compound is an important industrial chemical chiefly used to produce the polymer polyvinyl chloride pvc. Vinyl chloride also known as vinyl chloride monomer vcm and chloroethene is an organochloride compound.

Intermediates products and co products produced. Consequently man made chcs are beginning to accumulate in the environment. Chlorinated hydrocarbons chcs are much more resilient to biodegradation unlike simple hydrocarbons. 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.

Vinyl chloride monomer vcm is the key material from which pvc is made. Chlorinating hydrocarbons is the basic idea behind the production of vinyl chloride monomer vcm. Vinyl chloride monomer vcm production and manufacturing process 2010 04 28 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. Vcm is a major commodity chemical mainly used in the production of the polymer.

Vinyl chloride monomer vcm is a colorless gas with a faint odor. Vinyl chloride monomer vcm c2h3ci. Baton rouge la. Vinyl chloride was first produced in 1835 but did not go into regular production until the early twentieth century.

Vinyl chloride monomer vcm production. Direct chlorination and oxychlorination.
