How do you make a monomer of vinyl chloride?
The five main processes used in the production of vinyl chloride monomer (VCM) are: (1) direct chlorination of ethylene to form EDC, (2) oxychlorination of ethylene to form from recycled HCl and oxygen, (3) purification of EDC, (4) thermal cracking of EDC to form VCM and HCl, and (5) the purification of VCM.
What are the raw materials for the production of vinyl chloride?
Vinyl chloride monomer (VCM) is the key chemical precursor to PVC. It is produced commercially by combining a hydrocarbon feedstock, namely ethylene, obtained by cracking natural gas or petroleum, with elemental chlorine. Chlorine is derived from brine – a solution of common salt and water.
Where is vinyl chloride produced?
It can be formed in the environment when soil organisms break down chlorinated solvents. Vinyl chloride that is released by industries or formed by the breakdown of other chlorinated chemicals can enter the air and drinking water supplies. Vinyl chloride is a common contaminant found near landfills.
Is vinyl chloride a monomer?
Vinyl Chloride Monomer (VCM) is a colorless, flammable gas at room temperature. Its chemical formula is C2H3Cl. It is primarily used to manufacture polyvinyl chloride (PVC), a very stable, non-flammable, lightweight and durable plastic. PVC is used in a variety of applications.
What happens when vinyl chloride reacts with HCL?
It is addition reaction.
What products have vinyl chloride?
Vinyl chloride is an intermediate in the production of PVC plastic used in a wide range of products including pipes, wire and cable coatings, packaging materials, upholstery for automobiles and furniture, wall and floor coverings, flooring, backing for carpet, house wares, automotive parts, medical devices, and …
Is vinyl chloride a carcinogen?
Vinyl chloride has been found in the air near vinyl chloride manufacturing and processing plants, hazardous waste sites, and landfills. This toxic chemical is a known human carcinogen causing liver cancer, brain cancer and some cancers of the blood. Vinyl chloride has also been associated with mammary (breast) cancer.
What are the harmful effects of vinyl chloride?
Vinyl chloride exposure is associated with an increased risk of a rare form of liver cancer (hepatic angiosarcoma), as well as brain and lung cancers, lymphoma, and leukemia.
What is the formula of vinyl chloride?
C2H3Cl
Vinyl chloride/Formula
Why does pyridine react with HCl?
Reaction with HCl involves using the lone pair on nitrogen to form a bond to H. Pyrrolidine isn’t aromatic to begin with and the nitrogen lone pair doesn’t contribute to the aromaticity of pyridine. Thus, these two compounds undergo reaction with HCl.
How do you protect vinyl chloride?
What are the top tips to avoid exposure?
- Limit use of PVC plastic containers and food packaging, as they may have traces of vinyl chloride.
- Industrial workers in close contact with vinyl chloride should use respirators and wear protective clothing.
- Avoid tobacco smoke[11]
What are the harmful effect of vinyl chloride?
What products contain vinyl chloride?
Polyvinyl chloride is used to manufacture a wide variety of plastic and vinyl products like pipes, wire and cable coatings and packaging materials. In smaller amounts, vinyl chloride is also found in furniture, automobile upholstery, wall coverings, housewares and automotive parts.
What does vinyl chloride mean?
Vinyl Chloride. Vinyl chloride is a colorless, flammable gas that evaporates very quickly. It’s used to make polyvinyl chloride (PVC) pipes, wire coatings, vehicle upholstery, and plastic kitchen ware. Higher than normal levels of vinyl chloride may be present inside new cars as the chemical evaporates from new vinyl products.
What is the chemical equation for vinyl chloride?
The formula of the chemical compound Vinyl chloride is C2H3Cl
What is the chemical structure of PVC?
PVC is Polyvinyl Chloride . This is a plastic that has the following chemical formula: CH2=CHCl (see picture on the right). Plastic covers a wide rage of synthetic or semi-synthetic polymerization products (i.e. long-chain carbon-based “organic” molecules) which name refers to the fact that in their semi-liquid…
