In the direct chlorination as well as in the oxychlorination process ethylene dichloride edc is produced.
Vinyl chloride monomer production process.
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 process is referred to as the balanced process.
Vinyl chloride also known as vinyl chloride monomer vcm and chloroethene is an organochloride compound.
Pvc has the advantage of being utilized in conversion and fabrication processes with great flexibility such that end products cover a wide.
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.
Vinyl chloride was first produced in 1835 but did not go into regular production until the early twentieth century.
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 one of the world s most important and largest commodity chemicals.
The five main processes used in the production of vinyl chloride monomer vcm.
Vinyl chloride 99 of vcm is used to manufacture polyvinyl chloride pvc.
Direct chlorination by itself is a process that operates at lower temperatures and.
Vcm production results in a number of unwanted.
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 monomer summary vinyl chloride monomer vcm is a colorless flammable gas at room temperature.
About 13 billion kilograms are produced annually.
The process chosen for vinyl chloride production is a combination of two processes direct chlorination and oxychlorination.
Pvc is used in a variety of applications.
Its chemical formula is c2h3cl.
Vcm is a major commodity chemical mainly used in the production of the polymer.
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.
