Vinyl Chloride Monomer Production Process

Vcm production results in a number of unwanted.

Vinyl chloride monomer production process.

In the direct chlorination as well as in the oxychlorination process ethylene dichloride edc is produced. Pvc has the advantage of being utilized in conversion and fabrication processes with great flexibility such that end products cover a wide. 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. This process is referred to as the balanced process.

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 was first produced in 1835 but did not go into regular production until the early twentieth century. Vcm is used primarily for the production of polyvinyl chloride pvc homopolymer and copolymer resins. Vinyl chloride also known as vinyl chloride monomer vcm and chloroethene is an organochloride compound.

It is primarily used to manufacture polyvinyl chloride pvc a very stable non flammable lightweight and durable plastic. The vinnolit process for the production of vinyl chloride monomer vcm from ethylene and chlorine proceeds via two different routes. A method for the production of vinyl chloride monomer by catalytic oxychlorination of ethane wherein hcl is supplied in excess of the stiochiometric requirement for chlorine in the reaction. Direct chlorination by itself is a process that operates at lower temperatures and.

Vinyl chloride monomer summary vinyl chloride monomer vcm is a colorless flammable gas at room temperature. Pvc consumption is second to low density polyethylene. Vinyl chloride monomer vcm is one of the world s most important and largest commodity chemicals. Vcm is a major commodity chemical mainly used in the production of the polymer.

Its chemical formula is c2h3cl. 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. About 13 billion kilograms are produced annually. The process chosen for vinyl chloride production is a combination of two processes direct chlorination and oxychlorination.

Vinyl chloride 99 of vcm is used to manufacture polyvinyl chloride pvc.
