Vinyl Chloride Monomer Production

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.

Vinyl chloride monomer production. There are two methods to produce vcm. This is due mainly to the inherent strength of the c cl bond. Vinyl chloride also known as vinyl chloride monomer vcm and chloroethene is an organochloride compound. Pvc is the world s third most widely produced synthetic plastic polymer after polyethylene and polypropylene about 40 million tons of pvc are produced each year.

Pvc comes in two basic forms. 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. Vcm is used primarily for the production of polyvinyl chloride pvc homopolymer and copolymer resins. Direct chlorination and oxychlorination.

Rigid sometimes abbreviated as rpvc and flexible. Vinyl chloride monomer vcm is the key material from which pvc is made. Consequently man made chcs are beginning to accumulate in the environment. Chlorinated hydrocarbons chcs are much more resilient to biodegradation unlike simple hydrocarbons.

Pvc has the advantage of being utilized in conversion and fabrication processes with great flexibility such that end products cover a wide. Pvc is used in a variety of applications. Edc is then. Vcm is a major commodity chemical mainly used in the production of the polymer.

Vinyl chloride monomer vcm production. 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. Chlorinating hydrocarbons is the basic idea behind the production of vinyl chloride monomer vcm. 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 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. It is primarily used to manufacture polyvinyl chloride pvc a very stable non flammable lightweight and durable plastic. Direct chlorination sees ethylene and chlorine react within a catalyst containing reactor to form edc. About 13 billion kilograms are produced annually.

Vinyl chloride was first produced in 1835 but did not go into regular production until the early twentieth century.
