Vinyl Chloride Monomer Production

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.

Vinyl chloride monomer production.

Consequently man made chcs are beginning to accumulate in the environment. Intermediates products and co products produced. Direct chlorination and oxychlorination. Vinyl chloride monomer vcm is the key material from which pvc is made.

Vinyl chloride monomer vcm c2h3ci. Suspension pvc resins vinyl chloride monomer vcm point comfort tx. Edc is then. Vcm is used primarily for the production of polyvinyl chloride pvc homopolymer and copolymer resins.

It forms a liquid readily under increased pressure or at reduced temperatures. Chlorinated hydrocarbons chcs are much more resilient to biodegradation unlike simple hydrocarbons. 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. 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 a major commodity chemical mainly used in the production of the polymer. 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. About 13 billion kilograms are produced annually. This is due mainly to the inherent strength of the c cl bond.

Pvc has the advantage of being utilized in conversion and fabrication processes with great flexibility such that end products cover a wide. Vcm is used primarily in the production of polyvinyl chloride pvc homopolymer and copolymer resins. Vinyl chloride monomer vcm production. Chlorinating hydrocarbons is the basic idea behind the production of vinyl chloride monomer vcm.

Vinyl chloride monomer vcm is a colorless gas with a faint odor. Vinyl chloride was first produced in 1835 but did not go into regular production until the early twentieth century. Caustic chlorine ethylene ethylene dichloride edc vinyl chloride monomer vcm suspension pvc resins specialty dispersion pvc resins. Vinyl chloride monomer vcm is one of the world s most important and largest commodity chemicals.

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. Baton rouge la.
