Vinyl Chloride Monomer Production

Direct chlorination sees ethylene and chlorine react within a catalyst containing reactor to form edc.

Vinyl chloride monomer production. Pvc has the advantage of being utilized in conversion and fabrication processes with great flexibility such that end products cover a wide. 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. It forms a liquid readily under increased pressure or at reduced temperatures. Direct chlorination and oxychlorination.

Vinyl chloride was first produced in 1835 but did not go into regular production until the early twentieth century. There are two methods to produce vcm. Chlorinated hydrocarbons chcs are much more resilient to biodegradation unlike simple hydrocarbons. Vinyl chloride monomer vcm is one of the world s most important and largest commodity chemicals.

Consequently man made chcs are beginning to accumulate in the environment. Vinyl chloride monomer vcm is the key material from which pvc is made. Vinyl chloride monomer vcm c2h3ci. Baton rouge la.

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 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. This is due mainly to the inherent strength of the c cl bond. 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 is a colorless gas with a faint odor. About 13 billion kilograms are produced annually. Vinyl chloride monomer vcm production. 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. Vinyl chloride also known as vinyl chloride monomer vcm and chloroethene is an organochloride compound. Caustic chlorine ethylene ethylene dichloride edc vinyl chloride monomer vcm suspension pvc resins specialty dispersion pvc resins. Intermediates products and co products produced.

Vcm is a major commodity chemical mainly used in the production of the polymer. Suspension pvc resins vinyl chloride monomer vcm point comfort tx.
