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.
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 ...
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 ...
The EPA says long-term exposure to vinyl chloride by inhaling or through oral contact in humans has led to instances of liver damage and cancer, and its use has been banned in aerosols, drugs and ...
The first commercial application of photoionization detection was in 1973 as a hand-held instrument for the purpose of detecting leaks of VOCs, specifically vinyl chloride monomer (VCM), at a chemical manufacturing facility. The photoionization detector was applied to gas chromatography (GC) three years later, in 1976. [5]

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.
