Vinyl chloride is an organochloride with the formula H 2 C=CHCl. It is also called vinyl chloride monomer (VCM) or chloroethene. It is an important industrial chemical chiefly used to produce the polymer polyvinyl chloride (PVC). Vinyl chloride is a colourless flammable gas that has a sweet odor and is carcinogenic.
In the early 1970s, the carcinogenicity of vinyl chloride (usually called vinyl chloride monomer or VCM) was linked to cancers in workers in the polyvinyl chloride industry. Specifically workers in polymerization section of a B.F. Goodrich plant near Louisville, Kentucky , were diagnosed with liver angiosarcoma also known as hemangiosarcoma , a ...
In polymer chemistry, polymerisation inhibitors (US: polymerization inhibitors) are chemical compounds added to monomers to prevent their self-polymerisation. Unsaturated monomers such as acrylates, vinyl chloride, butadiene and styrene require inhibitors for both processing and safe transport and storage.
Vinyl polymers are the most common type of plastic. Important examples can be distinguished by the R group in the monomer H 2 C=CHR: Polyethylene R = H; polypropylene from propylene, R = CH 3; Polystyrene is made from styrene, R = C 6 H 5; Polyvinyl chloride (PVC) is made from vinyl chloride, R= Cl; Polyvinyl acetate (PVAc) is made from vinyl ...
Approximately 95% of the world's production of 1,2-dichloroethane is used in the production of vinyl chloride monomer (VCM) with hydrogen chloride as a byproduct. VCM is the precursor to polyvinyl chloride. ClC 2 H 4 Cl → H 2 C=CHCl + HCl. The hydrogen chloride can be re-used in the production of more 1,2-dichloroethane via the ...
Multiple cars containing vinyl chloride spilled their contents onto the ground, which is suspected of leading to contamination of the water, and the air after a fire. Studying vinyl chloride's ...
An industrially important example is vinyl chloride, precursor to PVC, [3] a plastic commonly known as vinyl. Chessboard made from polyvinyl chloride. Vinyl is one of the alkenyl functional groups. On a carbon skeleton, sp 2-hybridized carbons or positions are often called vinylic. Allyls, acrylates and styrenics contain vinyl groups.
