Vinyl Chloride Monomer Production

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

Vinyl chloride monomer production.

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 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. Intermediates products and co products produced.

Chlorinating hydrocarbons is the basic idea behind the production of vinyl chloride monomer vcm. Chlorinated hydrocarbons chcs are much more resilient to biodegradation unlike simple hydrocarbons. Baton rouge la. It forms a liquid readily under increased pressure or at reduced temperatures.

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. Edc is then. Consequently man made chcs are beginning to accumulate in the environment. Vinyl chloride monomer vcm is a colorless gas with a faint odor.

Vinyl chloride monomer vcm c2h3ci. There are two methods to produce vcm. Suspension pvc resins vinyl chloride monomer vcm point comfort tx. Vinyl chloride monomer vcm is the key material from which pvc is made.

Vcm is used primarily in the production of polyvinyl chloride pvc homopolymer and copolymer resins. Vinyl chloride monomer vcm production. Vinyl chloride also known as vinyl chloride monomer vcm and chloroethene is an organochloride compound. 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 was first produced in 1835 but did not go into regular production until the early twentieth century. 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 for the production of polyvinyl chloride pvc homopolymer and copolymer resins. Pvc has the advantage of being utilized in conversion and fabrication processes with great flexibility such that end products cover a wide.

Caustic chlorine ethylene ethylene dichloride edc vinyl chloride monomer vcm suspension pvc resins specialty dispersion pvc resins. About 13 billion kilograms are produced annually.
